Analysis of approximate solutions of coupled dynamical thermoelasticity and related problems. (English) Zbl 0627.73002
The paper deals with existence and uniqueness of solutions of various variational formulations of coupled dynamical thermoelasticity and with the convergence of approximate solutions. The first part deals with semidiscrete approximate solutions which are obtained by time discretization of the original variational problem. In the second part the authors consider in addition discretization in space by the finite element method. In the third part the weakest assumptions possible are imposed which require a different definition of the variational solution.
