Оценка деформируемости материала заготовок, полученных отделением методами пластического сдвига

Abstract

General relationships of the tensor model of damage accumulation in metals under complex two-stage deformation are obtained. Model of a two-stage deformation in a "shift - Compression" investigated. The relation for the residual life of plasticity in the second stage under the condition of exhaustion of the resource of plasticity at the first stage was obtained and studied. The results of experiments on the original scheme of a two-stage deformation "shear strain as a result cut of of the bead - the uniform axial-symmetric compression" are presented. The mathematical modeling of complex two-stage deformation in a sequence of "simple-complex" for a combination of a shift - in conditions of barrel distortion realized. The developed criteria allow estimate the deformability of the blanks that had been produced wasteless methods of shear segments.
