Numerical simulation of continuous damage and fracture in metal-forming processes with 3D mesh adaptive methodology
Résumé
An h-adaptive remeshing scheme dedicated to the simulation of cracked structures due to the ductile damage such as metal forming processes is proposed. Cracks are represented using a procedure based on fully damaged elements deletion. Element size inside the domain and along the crack path, is driven by error indicators based on geometrical considerations and the derivatives of physical quantities calculated by Diffuse Approximation and specific fields transfer procedures and an automatic adaptation of the time loading sequences are proposed. Emphasis is put on the remeshing issues.
