О выборе критериев разрушения в задачах обработки металлов давлением

Abstract

In this work we studied the effect of applying the criteria of destruction in the problems of metal forming the final result of research. The analysis of the data obtained by criteria G.A. Smirnov­Alyaev, V.L. Kolmogorov and V.A. Ogorodnikov. Substantiates the appropriateness of applying the criteria of destruction in the problems of metal forming. It is determined by the rate of damage accumulation and the curvature of the path of deformation. The recommendations for the application of the criteria G.A. Smirnov­Alyaev, V.L. Kolmogorov and V.A. Ogorodnikov in tasks pressure treatment. Designed route drawing wires into account the rate of accumulation of damage. The engineering formulas used to estimate the plasticity resource in forming taps of materials with different hardenability
