Non-linear dynamic fragmentation using Cracking Particles Method

We study the dynamic fracture of thin metal rings with the Cracking Particles Method (CPM). The CPM models the crack as set of straight crack segments and does not require track cracking algorithms. No empirical criteria for branching and joining cracks as in method with continuous crack surface are required. The constitutive behavior is considered non-linear in this contribution. Our methodology is used for several experimental set-ups in order to study the influence of different parameters such as the loading rate, the strain-to-fracture, the fracture energy, among others. The results are compared to results based on linear elasticity.
