Numerical aspects of a remeshing strategy towards threedimensional ductile damage simulations

A proper modelling and understanding of ductile damage and fracture gives us the capability to predict the behavior of metals and alloys in extreme loading cases. Fracture is the final stage of this behavior and a three dimensional modelling provides us with a comprehensive tool to predict it in a realistic manner. Here we focus on three different aspects of numerical modelling: (ielement technology, (iiremeshing issues and (iii3D crack insertion. Each aspect is developed and evaluated independently and finally the combination of them is used for the modelling of large deformation three dimensional crack initiation and propagation
