Abstract
A finite element model for the simulation of fast crack propagation under dynamic Mode I load conditions is developed. The principal tools are an enhanced strain formulation and a quasi-contact algorithm. Crack propagation is controlled by the implemented fracture criterion. The model accounts for viscoplastic material behavior, dynamic effects and contact in the crack zone. The numerical results demonstrate that these physical effects are of major importance when load speed is increased to a high level and therefore they cannot be neglected.
