Data acquisition from FEM simulations. (A) The domain J-integral method is used to evaluate the stress intensity factor at the crack tip. An encastrĂ© boundary condition is applied to the fixed end of the cantilever and a displacement-controlled boundary condition to the free end. (B) The computational time of the 3D simulation can be reduced by parallel computing. A typical simulation takes ∼100 s when running in parallel on 16 CPUs with FEAP.
