Anisotropic fracture modeling of 3D-printed samples

The phase-field fracture method is a computational framework for modeling cracks using a regularized continuous field rather than introducing sharp discontinuities. This regularization enables the simulation of complex crack patterns without the need for explicit tracking of crack surfaces. This presentation focuses on the application of the phase-field fracture method to simulate crack initiation and propagation in 3D-printed brittle materials. We show the effects of the printing direction and infill density on the fracture behavior of 3D-printed materials.
