Abstract
A crack growth criterion is derived based on the Griffith energy concept and the cohesive zone model for modelling fracture in elastic-plastic ductile materials. The criterion is implemented in the finite element context by a virtual crack extension technique. An automatic modelling of the ductile fracture process is realised by combining a local remeshing procedure and the criterion. The validity of the derived criterion is examined by modelling a compact tension specimen.
