Abstract
In the framework of mechanics of damaged media (MDM), a mathematical model describing creep-induced processes of inelastic deformation and damage accumulation is developed. The MDM model consists of three interrelated parts: relations defining inelastic behavior of the material, accounting for its dependence on the failure process; equations describing damage accumulation kinetics; a strength criterion of the damaged material.The results of experimentally studying short-term creep of the VZh-159 heat-resistant alloy at constant temperature values and different values of applied stresses in the specimens are given.Comparison of the numerical and experimental results makes it possible to conclude that the proposed defining relations of MDM are reliable in describing degrading initial strength properties of structural materials according to the long strength mechanism.
