摘要：
A model for investigations of thermal effects in elastoviscoplastic bodies has been developed. It allows to obtain some quantitative and qualitative information on stress-strain state of the body and to carry out a nondestructive diagnostics of internal defects such as stress and strain concentrators. The problem of plane stress state of a rectangule with a hole is considered. Steel 12KhN3A and aluminum alloys AMg-6 are used as the plate material. Peculiarities of temperature change on the exteriour boundaries of the body under its monotonous or cyclic extension in the elastic and plastic regions have been studied.
