Extending the Thick Level Set Approach: Plasticity, Parallel Computing and Cohesive Cracks

Autor: Taumaturgo Mororo, L.A.

Developing accurate and robust numerical approaches that are capable of modeling fracture in solids has been a challenging undertaking in the computational mechanics community for decades. Models based on a continuous formulation or on a discontinuou

International audience; The prediction of the load of a structure with a defect remains to this day a great challenge. In this study, we propose to highlight the harmfulness of a sharp V-notch through a comparative study of the stress to failure obta

The Thick Level Set method (TLS) is an approach for non-local damage modeling in which the damage evolution is linked to the movement of a damage front described with the level set method. More recently, a new version of the TLS, designated as the TL
