Elastic-plastic bending of three-layer rods under single and variable loading, taking into account damage and temperature effects

Abstract

The article provides a scheme for calculating the deformation of three-layer elastoplastic rods with a rigid filler that are asymmetrical in thickness under single and variable loading, taking into account damage and temperature effects. Based on the Lagrange variational principle, the problem of bending three-layer rods under single and alternating loading is formulated. An approximate method based on the method of elastic solutions is used to solve the problems. The calculated values for three-layer rods are given, taking into account the cyclic characteristics of the materials, the accumulation of damage and the influence of temperature.
