Numerical simulation of the stress state taking into account the kinetics of phase transformations in a butt welded joint of steel dc04 for different technological welding schemes

Для моделі стикового зʼєднання зі сталі DC04 розмірами 600х600х10 мм методом скінченних елементів розв’язана нестаціонарна задача термопружнопластичності з урахуванням фазових перетворень при однопрохідному зварюванні під флюсом стикового шва. Для трьох технологічних схем зварювання представлені результати дослідження напруженого стану з урахуванням розподілу фазового складу у шві в залишковому стані, які мають науково-практичну цінність для прогнозування безпечної роботи зварних конструкцій.For the model of butt welded joint made from steel DC04 with dimensions: 600x600x10 mm, a non-stationary thermoelastoplasticity problem, which takes into account phase transformations during single-pass submerged arc welding, was solved by means of the finite element method. For three technological welding schemes, the results of study of the stress state are presented, taking into account the distribution of the phase composition in the weld in the residual state, which have important scientific and practical interest in terms of predicting the safe operation of the welded structures

INTERACTION OF IHRL AND IHL IN THE FIELD HUMAN RIGHTS PROMOTION: INTERNATIONAL STANDARDS AND NATIONAL DIMENSION

The urgency of the research is conditioned by the actual status of the governmental and legal reality of Ukraine which is in conditions of the armed conflict seventh year in a row resulting in the need to ensure both state sovereignty and guarantee and protection of human rights. In this regard, the article is aimed at studying the interaction of international human rights law and international humanitarian law, as well as their implementation in the legislation of Ukraine in conditions of an armed conflict. Scientific methods of research of the declared problems are the system method by means of which the international human rights law and the international humanitarian law are considered as two systems of more difficult complex – the international law. Using the structural-functional method, the structure and mechanisms of functional interaction of these systems on the legal regulation in the field of human rights in specific conditions are studied. The article analyzes the legal basis of international human rights law and international humanitarian law, as well as their possible simultaneous application in the context of the armed conflict in eastern Ukraine. Emphasis is placed on the need to ensure compliance with the principles of international humanitarian law and to bring to justice those guilty of violating the rules of the IHRL and IHL. The research results can be used in the educational process and further research
