Concurrent mesh and model adaptive modeling of crack propagation

Résumé

This paper presents a concurrent mesh and model adaptive approach that ensure both the quality and the optimality in the numerical modelling of crack propagation in large thin curved structures. Time dependent evolving mesh is used to follow up crack advancing and to concentrate finite elements of small enough size around the path of crack propagation. To correctly account for three dimensional (3D) effects occurring around crack tip in thin structures that are meshed with shell elements, model adaptivity is performed so small 3D meshes surrounding crack tips and moving together with cracks are adaptively introduced.
