Novel Techniques for Modeling 3D Cracks

Novel techniques for modeling 3D cracks and their evolution in solids are presented. Cracks are modeled in terms of signed distance functions (level sets).

Methodology

Stress, strain and displacement field are determined using the extended finite elements method (X-FEM).

Non-Linear Behavior

Non-linear constitutive behavior for the crack tip region are developed within this framework to account for non-linear effect in crack propagation.

Applications

Applications for static or dynamics case are provided.
