Dynamic Fracture in Thin Shells Using Meshfree Method

Dynamic Fracture in Thin Shells Using Meshfree Method

We present a meshfree approach to model dynamic fracture in thin structures. Material failure is modeled based on a stress-based criterion and viscoplastic is used to describe the material behavior in the bulk material. Material fracture is simply modeled by breaking bonds between neighboring partic...
