Axiological chaos and unsustainable man’s acting in a contemporary world has led him to a total confusion. He constantly acts toward environmental and cultural degradation. Also in social dimension a permanent and “general” crisis dominates. The crisis is rooted on multi-category stratification and based on post-truth models of interpersonal communication in traditional and virtual realities. Neoliberal model of economical conquest, in turn, effects unsustainability in economic sphere. Thus, in common reception – for the most people in the world – such situation has become unbearable. So, it is the educators’ duty to look for – with the intention to put into practise – such concepts and pedagogies, which could prepare the whole global society to real – not declaratory false – co-creation of its life in the world, understood as an actual and common home. Taking such perspective, the theory of Argentinian philosopher – Ernesto Laclau becomes an interesting proposition. The time of mono-dimensional – protestant and neoliberal – interpretation of values comes to the end. Now the time has come to accept the equality of different – having their roots in various cultures – value understanding. Possibility of local and particular interpretation of values – along with maintaining the rule of common good – gives the chance to update the education according to real, thus multidimensional humanistic ideal. Such a standpoint presents a way to cure/reform intercultural education, which nowadays is at an impasse. Mainly it uses stiff schemes and repeated patterns, so it has become imitative and conservative. In its contemporary formula intercultural education is not able to respond to present challenges of multicultural and global society. The need to implant into its structure the concept of sustainable development emerges as a must.
This paper presents a numerical investigation of fracture criterion influence on perforation of high-strength 30PM steel plates subjected to 7.6251 mm Armour Piercing (AP) projectile. An evaluation of four ductile fracture models is performed to identify the most suitable fracture criterion. Included in the paper is the Modified Johnson-Cook (MJC) constitutive model coupled separately with one of these fracture criteria: the MJC fracture model, the Cockcroft-Latham (CL), the maximum shear stress and the constant failure strain models. A 3D explicit Lagrangian algorithm that includes both elements and particles, is used in this study to automatically convert distorted elements into meshless particles during the course of the computation. Numerical simulations are examined by comparing with the experimental results. The MJC fracture model formulated in the space of the stress triaxiality and the equivalent plastic strain to fracture were found capable of predicting the realistic fracture patterns and at the same time the correct projectile residual velocities. However, this study has shown that CL one parameter fracture criterion where only one simple material test is required for calibration is found to give good results as the MJC failure criterion. The maximum shear stress fracture criterion fails to capture the shear plugging failure and material fracture properties cannot be fully characterized with the constant fracture strain.
The Koran became an inspiration to the Russian poet Alexander Pushkin (1799–1837), made obvious in many of his works, such as Imitations of the Koran, The Prophet, and In a Secret Cave. Pushkin studied the translation of the Koran carefully and used many verses of its Surahs in his texts. Many of his contemporary poets and followers were influenced by his poetry, like Ivan Bunin (1870–1953), who continued the traditions of Pushkin. Bunin repeated many thoughts from Koranic discourse and placed them in his poems that were full of faith and spirituality. He wrote many of them at the beginning of the 20th century1, before his emigration to France in 1918, for example: Mohammed in Exile, Guiding Signs and For Treason. It has been noted that Bunin was quoting verses from the Koran to create an intertextual relationships between some Surahs and his poems, showing a great enthusiasm to mystical dimension of Islam. We find this aspect in many works, such as The Night of al-Qadr, Tamjid, Black Stone of the Kaaba, Kawthar, The Day of Reckoning and Secret. It can also be said that a spiritual inspiration and rhetoric of Koran were not only attractive to Pushkin and Bunin, but also to a large group of Russian poets and writers, including Gavrila Derzhavin, Mikhail Lermontov, Fyodor Tyutchev, Yakov Polonsky, Lukyan Yakubovich, Konstantin Balmont, and others.
