The Influence of a Degree of Initial Material Defects on the Strain Structure Formed in the Explosive Collapsing Thick-Walled Cylinders

Abstract

Abstract. The iduence of preliminaty shock-wave loading on the defonnation structure formation in the process of following high-rate plastic strain has been investigated. The previous hardening is shown to provide a stmmd uniformity of the defonnation to large value of strain due to the formation of a highly dispersed intergrain structure.R6surnB: L'influence de chargement prelimhaire par ondes de choc sur la formation de la structure dt5fomke lors de la deformation plastique u!t&rieure B grande vitesse de d6formation est 6tudibe.
