Abstract

A mathematical model for studying the thermal elastic and plastic stress-strain state and the strength of the rocket equipment systems at restarts has been proposed using the heat conductivity equations and the constitutive equations of thermal plasticity for repeated elastic-plastic strains of isotropic materials along small-curvature trajectories, the strength and low-cyclic fatigue criteria, numerical methods for solving the boundary heat conductivity problems, as well as special software.
