In this paper, thermally-excited, lateral free vibration analysis of a small-sized Euler-Bernoulli beam is studied based on the nonlocal theory. Nonlocal effect is exerted into analysis utilizing differential constitutive model of Eringen. This model is suitable for design of sensors and actuators in dimensions of micron and submicron. Sudden temperature rise conducted through the thickness direction of the beam causes thermal stresses and makes thermo-mechanical properties to vary. This temperature field is supposed to be constant in the lateral direction. Temperatures of the top and bottom surfaces of the system are considered to be equal to each other. Governing equation of motion is derived using Hamilton’s principle. Numerical analysis of the system is performed by Galerkin’s approach. For verification of the present results, comparison between the obtained results and those of benchmark is reported. Numerical results demonstrate that dynamic behavior of small-sized system is been effected by temperature shift, nonlocal parameter, and slenderness ratio. As a result, taking the mentioned parameters into account leads to better and more reliable design in miniaturized-based industries.

In the paper, the extended finite element method (XFEM) is combined with a recovery procedure in the analysis of the discontinuous Poisson problem. The model considers the weak as well as the strong discontinuity. Computationally efficient low-order finite elements provided good convergence are used. The combination of the XFEM with a recovery procedure allows for optimal convergence rates in the gradient i.e. as the same order as the primary solution. The discontinuity is modelled independently of the finite element mesh using a step-enrichment and level set approach. The results show improved gradient prediction locally for the interface element and globally for the entire domain.

The paper presents the response of a three-layered annular plate with damaged laminated facings to the loads acting in their planes. The presented problem concerns the analysis of the combination of global plate failure in the form of buckling with the local micro defects, like fibre or matrix cracks, located in the laminas. The plate structure consists of thin laminated, fibre-reinforced composite facings and a thicker foam core. The matrix and fibre cracks of facings laminas can be transversally symmetrically or asymmetrically located in plate structure. Critical static and dynamic stability analyses were carried out solving the problem numerically and analytically. The numerical results show the static and dynamic stability state of the composite plate with different combinations of damages. The final results are compared with those for undamaged structure of the plate and treated as quasi-isotropic ones. The analysed problem makes it possible to evaluate the use of the non-ideal composite plate structure in practical applications.

Centrifugal pumps are used for different applications that include pressure boosting, wastewater, water supply, heating and cooling distribution and other industrial processes. This paper presents theoretical and experimental investigations of mechanical vibrations of a centrifugal pump. The flow in this pump, which induces pressure pulsations and mechanical vibrations, have been monitored. Vibration measurements and data collection (overall vibrations levels and frequency spectrum) were extracted from the system. In addition, one of the methods used to study vibration amplitudes for this pump is forced response analysis. To study and analyze the pump system, the finite element analysis software (ANSYS) was applied. Depending on the analysis performed and investigations outcomes, the system natural frequency coincides with the vane-pass frequency (VPF) hazardously. To attenuate the system’s vibration, a vibration control element was used. The vibration levels were reduced by a factor of 2 for a tuned element as obtained from a forced harmonic response analysis of the pump system with absorber. It is shown that the inserted element allows the centrifugal pump to work in a safe operating range without any interference with its operation.

The article presents the methodology to estimate the operator influence on measurements performed with a coordinate measuring arm. The research was based on the R&R analysis, adapted to the specifics of redundant devices such as ACMM (selection of a test object difficult to measure). The method provides for measurements by three operators, who measure ten parts in two or three samples (measurement data developed in the article relate to the three measurements of holes). The methodology is designed to identify which operator has the best predisposition to perform measurements (generates the smallest measurement errors). Statistica software was used to analyse and visualize measurement data.

An optimal sensor placement methodology is implemented and herein proposed for SHM model-assisted design and analysis purposes. The kernel of this approach analysis is a genetic-based algorithm providing the sensor network layout by optimizing the probability of detection (PoD) function while, in this preliminary phase, a classic strain energy approach is adopted as well established damage detection criteria. The layout of the sensor network is assessed with respect to its own capability of detection, parameterized through the PoD. A distributed fiber optic strain sensor is adopted in order to get dense information of the structural strain field. The overall methodology includes an original user-friendly graphical interface (GUI) that reduces the time-to-design costs needs. The proposed methodology is preliminarily validated for isotropic and anisotropic elements.

About the Journal
Archive of Mechanical Engineering is an international journal publishing works of wide significance, originality and relevance in most branches of mechanical engineering. The journal is peer-reviewed and is published both in electronic and printed form. Archive of Mechanical Engineering publishes original papers which have not been previously published in other journal, and are not being prepared for publication elsewhere. The publisher will not be held legally responsible should there be any claims for compensation. The journal accepts papers in English.

Archive of Mechanical Engineering is an Open Access journal. The journal does not have article processing charges (APCs) nor article submission charges.

Outline of procedures
  • To ensure that high scientific standards are met, the editorial office of Archive of Mechanical Engineering implements anti-ghost writing and guest authorship policy. Ghostwriting and guest authorship are indication of scientific dishonesty and all cases will be exposed: editorial office will inform adequate institutions (employers, scientific societies, scientific editors associations, etc.).
  • To maintain high quality of published papers, the editorial office of Archive of Mechanical Engineering applies reviewing procedure. Each manuscript undergoes crosscheck plagiarism screening. Each manuscript is reviewed by at least two independent reviewers.
  • Before publication of the paper, authors are obliged to send scanned copies of the signed originals of the declaration concerning ghostwriting, guest authorship and authors contribution and of the Open Access license.
Submission of manuscripts

The manuscripts must be written in one of the following formats:
  • TeX, LaTeX, AMSTeX, AMSLaTeX (recommended),
  • MS Word, either as standard DOCUMENT (.doc, .docx) or RICH TEXT FORMAT (.rtf).
All submissions to the AME should be made electronically via Editorial System – an online submission and peer review system at First-time users must create an Author’s account to obtain a user ID and password required to enter the system. All manuscripts receive individual identification codes that should be used in any correspondence with regard to the publication process. For the authors already registered in Editorial System it is enough to enter their username and password to log in as an author. The corresponding author should be identified while submitting a paper – personal e-mail address and postal address of the corresponding author are required. Please note that the manuscript should be prepared using our LaTeX or Word template and uploaded as a PDF file.

If you experience difficulties with the manuscript submission website, please contact the Assistant to the Editor of the AME (

All authors of the manuscript are responsible for its content; they must have agreed to its publication and have given the corresponding author the authority to act on their behalf in all matters pertaining to publication. The corresponding author is responsible for informing the co-authors of the manuscript status throughout the submission, review, and production process.

Length and arrangement

Papers (including tables and figures) should not exceed in length 25 pages of size 12.6 cm x 19.5 cm (printing area) with a font size of 11 pt. For manuscript preparation, the Authors should use the templates for Word or LaTeX available at the journal webpage. Please notice that the final layout of the article will be prepared by the journal's technical staff in LaTeX. Articles should be organized into the following sections:
  • List of keywords (separated by commas),
  • Full Name(s) of Author(s), Affiliation(s), Corresponding Author e-mail address,
  • Title,
  • Abstract,
  • Main text,
  • Appendix,
  • Acknowledgments (if applicable),
  • References.
Affiliations should include department, university, city and country. ORCID identifiers of all Authors should be added.
We suggest the title should be as short as possible but still informative.

An abstract should accompany every article. It should be a brief summary of significant results of the paper and give concise information about the content of the core idea of the paper. It should be informative and not only present the general scope of the paper, but also indicate the main results and conclusions. An abstract should not exceed 200 words.

Please follow the general rules for writing the main text of the paper:
  • use simple and declarative sentences, avoid long sentences, in which the meaning may be lost by complicated construction,
  • divide the main text into sections and subsections (if needed the subsections may be divided into paragraphs),
  • be concise, avoid idle words,
  • make your argumentation complete; use commonly understood terms; define all nonstandard symbols and abbreviations when you introduce them;
  • explain all acronyms and abbreviations when they first appear in the text;
  • use all units consistently throughout the article;
  • be self-critical as you review your drafts.
The authors are advised to use the SI system of units.


You may use line diagrams and photographs to illustrate theses from your text. The figures should be clear, easy to read and of good quality (300 dpi). The figures are preferred in a vector format (bitmap formats are acceptable, but not recommended). The size of the figures should be adequate to their contents. Use 8-9pt font size of the text within the figures.

You should use tables only to improve conciseness or where the information cannot be given satisfactorily in other ways. Tables should be numbered consecutively and referred to within the text by numbers. Each table should have an explanatory caption which should be as concise as possible. The figures and tables should be inserted in the text file, where they are mentioned.

Displayed equations should be numbered consecutively using Arabic numbers in parentheses. They should be centered, leaving a small space above and below to separate it from the surrounding text.


We encourage authors to restrict the use of footnotes. Information concerning research grant support should appear in a separate Acknowledgements section at the end of the paper. Acknowledgements of the assistance of colleagues or similar notes of appreciation should also appear in the Acknowledgements section.

References should be numbered and listed in the order that they appear in the text. References indicated by numerals in square brackets should complete the paper in the following style:

English language

Archive of Mechanical Engineering is published in English. Make sure that your manuscript is clearly and grammatically written. The content should be understandable and should not cause any confusion to the readers, including the reviewers. After accepting the manuscript for a publication in the AME, we offer a free language check service, for correcting small language mistakes.

Submission of Revised Articles

When revision of a manuscript is requested, authors are expected to deliver the revised version of the manuscript as soon as possible. The manuscript should be uploaded directly to the Editorial System as an answer to the Editor's decision, and not as a new manuscript. If it is the 1st revision, the authors are expected to return revised manuscript within 60 days; if it is the 2nd revision, the authors are expected to return revised manuscript within 14 days. Additional time for resubmission must be requested in advance. If the above mentioned deadlines are not met, the manuscript may be treated as a new submission.

Outline of the Production Process

Once an article has been accepted for publication, the manuscript is transferred into our production system to be language-edited and formatted. Language/technical editors reserve the privilege of editing manuscripts to conform with the stylistic conventions of the journal. Once the article has been typeset, PDF proofs are generated so that authors can approve all editing and layout.


Proofreading should be carried out once a final draft has been produced. Since the proofreading stage is the last opportunity to correct the article to be published, the authors are requested to make every effort to check for errors in their proofs before the paper is posted online. Authors may be asked to address remarks and queries from the language and/or technical editors. Queries are written only to request necessary information or clarification of an unclear passage. Please note that language/technical editors do not query at every instance where a change has been made. It is the author's responsibility to read the entire text, tables, and figure legends, not just items queried. Major alterations made will always be submitted to the authors for approval. The corresponding author receives e-mail notification when a PDF is available and should return the comments within 3 days of receipt. Comments must be uploaded to Editorial System.


The Editorial Board of the Archive of Mechanical Engineering (AME) sincerely expresses gratitude to the following individuals who devoted their time to review papers submitted to the journal. Particularly, we express our gratitude to those who reviewed papers several times.
