The fracture mechanics calculation is used to evaluate key figures required for fracture mechanics verification. For simple geometric shapes, the key figures can be determined on the basis of analytical relationships. In other cases, we can determine these using a FEM simulation. For this purpose we use the SMART and XFEM calculation methods implemented in ANSYS®, which allows analysis not only of the first crack, but also crack propagation in any propagation direction.
