Abstract: In this paper we focus on the thermo-mechanical model which describes crack genesis and propagation in brittle materials induced by a thermal shock. Our goal is to provide an efficient numerical technique which employs a computational finite element mesh finely customized to the problem at hand to simulate such phenomena. In particular, we generate automatically adapted anisotropic grids able to closely follow the narrow bands of the damage, driven by a theoretically sound mathematical tool. We carry out two numerical tests to assess the computational performance of the proposed method.
