Topics on Modeling and Finite Element Prediction of Ductile Fracturing in Inelastic Solids

A framework for the finite element prediction of ductile fracturing initiation in inelastic solids undergoing large strains is suggested. Its essential components include the appropriate constitutive modeling of the material response under progressive damaging leading to fracture initiation. The definition of suitable error estimators maintains the spatial discretisation errors within acceptable bounds and the use of appropriate low-order finite element technology compatible with the demands of a multi-physics FE environment. At the end of the presentation, the limitations of continuum phenomenological constitutive models in the present context are critically reviewed. The use of multi-scale path-dependent constitutive models is outlined as a possible alternative to the classical phenomenological material characterization.
