On spectral approximation algorithm for thermoelastic shells in the nonclassical theory of thermoelasticity with three phase-lags
Résumé
In this paper nonclassical dynamical model for thermoelastic bodies with three phase-lags is studied. Applying variational formulation of the general three-dimensional initial-boundary value problem existence and uniqueness of solution in suitable spaces is proved. Spectral algorithm of approximation of the three-dimensional initial-boundary value problem for thermoelastic shell by a sequence of two-dimensional ones is constructed, convergence of the algorithm in corresponding spaces is proved and the rate of convergence is estimated.
