We simulate three point bending tests performed on lamination orthogonal and parallel. The layer lamination is represented through the fracture toughnss $G_c$ as shown below.
Simulated crack path (phase-field) for the lamination orthogonal and the parallel are shown below:
The responses of crack mouth opening displacement (CMOD) vs. force is as follows.
