NUMERICAL ANALYSIS OF THE THERMOELASTOPLASTIC STRESS-STRAIN STATE OF LAMINATED ORTHOTROPIC SHELLS UNDER AXISYMMETRIC LOADING

摘要

In this work, we consider the axisymmetric boundary-value problem of thermoplasticity for the laminated shells made of isotropic and orthotropic materials subjected to heating and loading. The equations of the plastic flow theory with isotropic hardening and the R. Hill flow theory are used. A method of successive approximations is developed to solve the problem. The components of stress-strain state of two laminated shells under loading and heating are obtained and represented graphically.
