Проведен анализ результатов экспериментально-теоретических исследований роли термомеханических эффектов при упругопластическом адиабатическом статическом и динамическом деформировании образцов из металлов и сплавов в зависимости от скорости и величины их деформации. Ключевые слова: работа пластической деформации, тепловая энергия, большие деформации, скорость деформации.
Abstract. It is proposed to develop experimental and calculated approach to the study of the strength characteristics of elastoviscoplastic materials in a non-uniform strain-stress state. Integral characteristics (forces, displacements and displacement speed) of the deformation process of hat-shaped specimens in tension are determined by a direct impact method, and their strain -stress states are determined by numerical solution of the axisymmetric problem. The results of experimental and theoretical study of the deformation and failure of hat-shaped specimens in the presence of stress concentrators are obtained.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
