On the Numerical Solution of a Class of Nonlinear Problems in Dynamic Coupled Thermoelasticity

摘要

The paper conerns the application of the finite-element method to the solution of certain nonlinear problems in thermoelasticity. Numerical solutions of transient, coupled thermoelasticity problems involving bodies which exhibit material nonlinearities and temperature-dependent thermal conductivity and specific heat are presented. General equations of motion and heat conduction of an arbitrary finite element are reduced so as to apply to the problem of transient response of a nonlinear thermoelastic half space subjected to a time-dependent temperature over its boundary.
