Development of the crack-line-update method for two-dimensional piercing simulations
2018
We have developed the crack-line-update method for two-dimensional piercing simulations by a finite element method. This method is combined with a remeshing process involving an outer line and meshing. By using the crack-line-update method, crack lines, which are derived from a stress and strain analysis of the high-damage regions, are added to the outer line in every remeshing step. In this paper, we compare the simulations between the mesh deletion and crack-line-update methods. The crack-line-update method successfully simulated the arresting of cracks during the piercing process, whereas the mesh deletion method could not express such fracture behavior.
