Solution method of dynamic creep-damage problem for beams bending

Abstract

Problems of numerical estimations of the strength of modern technology and elements of structures take an important place in their design, creation, test and operation. For many structural elements calculation schemes can be used in the form of thin-walled beams. Operating conditions of such structures are characterized by high levels of temperatures and dynamic loads. Under these conditions, due to such phenomena as creep and damage, there are limitations in the properties of strength and durability of such structural elements. Exploitation conditions in many cases of such structures elements correspond to action of quasi-static loadings and non-stationary physical and mechanical rapidly oscillating fields. So it is necessary to take into account dynamic effect in problem statement.
