Numerical method, existence and uniqueness for thermoelasticity system with moving boundary

Abstract: Abstract. In this work, we are interested in obtaining existence, uniqueness of the solution and an approximate numerical solution for the model of linear thermoelasticity with moving boundary. We apply finite element method with finite difference for evolution in time to obtain an approximate numerical solution. Some numerical experiments were presented to show the moving boundary's effects for problems in linear thermoelasticity. 35A05, 35A40, 65M60, 65M06. Mathematical subject classification:

“…Concerning mathematical free-boundary problems arising from singular interfaces, there are some results for a spatially onedimensional setting. We refer to [44,45] for application to solid mechanics and, for an application to moving reaction fronts in concrete, to [46][47][48]. Moreover, further challenges consist of developing suitable numerical algorithms and performing simulations in order to deal with applications.…”
