Generalized regularities of deformation and fracture processes

Аннотация

On February 9, 2016, the meeting of the RAS Presidium heard and discussed a paper by RAS Corresponding Member N.A. Makhutov on priority basic interdisciplinary research and applied developments in coupled resource substantiation and strength and safety of unique objects using generalized regularities of deformation and fracture processes. It is shown that the solution to the above objectives in relation to unique facilities used in traditional, atomic, and thermonuclear power engineering; the rocket and space complex; aviation; high-speed and heavy haul rail transport; as part of petrochemical equipment; and in shelf developments is associated with the necessity, in addition to traditional approaches, to consider the possibility of initiation and development of accidental and emergency situations. Therefore, modern calculations use simultaneously traditional (strength, service life, wear resistance, cold resistance, and seismic resistance) and new criteria (survivability, safety, and immunity using risk criteria). Through this, new fields of limit states associated with extreme external impacts and internal factors are analyzed.
