Three point bending test on anisotropic rock

Problem description

Note, this project file runs only with a modified version of OGS which you can find here.

We simulate three point bending tests performed on lamination orthogonal and parallel. The layer lamination is represented through the fracture toughness $G_c$ as shown below.

Results and evaluation

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.
