Numerical modelling of thermal shock processes is a very challenging task due to the rapid development of complex crack networks. In the context of linear elastic fracture mechanics, the scaled boundary finite element method (SBFEM) has gained popularity due to its semi‐analytical nature. Here, modelling of stress singularities can be achieved efficiently and accurately. It also facilitates the derivation of generalized polygon elements and thus provides great flexibility in meshing of complex geometries. In crack propagation modelling, such polygon meshes require minimal re‐meshing in the vicinity of the crack.
