Abstract : Integral-operator equations of creep and relaxation corresponding to A. Yu. i shlinskiy's generalized model of plane elastoplastic deformation with linear hardening of a compressible material are set up and analyzed. Using these equations, the peculiarities of relaxation in the elasticity and plasticity zones with hardening are studied. A study is made of the nature of the cha ge with respect to time of the radius of a plasticity zone (with linear hardening) located near a circular aperture cut in an infinite plane about the circumference of which a pressure is exerted.
