Abstract

Design considerations, material properties and dynamic properties of engineering applications, rotating components, turbine blades, helicopter blades, etc., have significant effects on system efficiency. Structures made of functionally graded materials have recently begun to take place in such engineering applications, resulting from the development of composite material technology. In this study, vibration and buckling characteristics of axially functionally graded beams whose material properties change along the beam length is analyzed. Beam structural formulations and functionally graded material formulations are obtained for the Classical and the First Order Shear Deformation Theories. Finite element models are derived to carry out the vibratory and stability characteristic analyses. Effects of several parameters, i.e., rotational speed, hub radius, material properties, power law index parameter and boundary conditions are investigated and are displayed in several figures and tables. The calculated results are compared with the ones in open literature and very good agreement is observed.

Abstract

Martin Heidegger in The Origin of the Work of Art (Der Ursprung des Kunstwerkes) developed a whole new way of thinking about art, going beyond traditionally understood aesthetics or even philosophy of art. Some of Heidegger’s thoughts, however, appear to be understated and only signal a huge complexity of both experiencing works of art and the very issue of the origin of the work of art. The analysis of the terms ‘dread’ and ‘eyeblink’ from Time and Being presented in this article complement and develop Heidegger’s ideas included in his essay. Linking art to these two crucial phenomena of fundamental ontological analysis of Dasein casts light on the status of art and its existential significance. The author aims mainly at demonstrating the aletheic connection (based on unclosedness) between the experience of ‘originary source’ of a piece of art and ‘dread’, and also, in conclusion, he points to the ‘event of Being’ as the essential, non-metaphysical origin of art.
