Abstract

An experimental-computational method is developed to study the stress state of a material on the basis of its experimental kinematic diagram by using the techniques of visioplasticity. The method of R-functions and the method of stress functions are used in calculating the stress state. Volumetric plastic deformation is also taken into account. The stress field for the initial (nonsteady) stage of extrusion of an axisymmetric porous semifinished product is obtained.
