Advanced remeshing techniques for complex 3D crack propagation
This paper is related to the development of an efficient numerical technique to simulate the propagation of 3D cracks that can evolve inside complex industrial structures due to intense fatigue loading.In this prospect,an adaptive remeshing approach is presented: based on an efficient mesh intersection algorithm,and using robust automatic meshers developed at INRIA,this approach allows to insert almost any kind of cracks in very complex meshes.Associated to a fast and accurate stress intensity factor evaluation,a kinking angle criterion and a fatigue propagation law,such remeshing algorithms allow to simulate complex crack growth phenomena (with coalescing multiple cracks,crack fronts splitting,contact in small deformation,etc.) in the context of linear elastic fracture mechanics.
