Analysis of stress-strain state inhomogenuity of metal during severe plastic deformation
In the present work the numerical simulation and experimental results for the following severe plastic deformation processes: equal channel angular pressing and 2D forging are presented. Two criteria - regularity of strain intensity distribution and rigidity coefficient of stressed state - were used for comparative analysis. Experimental research of severe plastic deformation processes was carried out by special ECA-pressing tool and GLEEBLE SYSTEM 3800 complex used for physical simulation of deformation processes.
