N2 - An incremental finite element model is presented that predicts the growth of a crack through a 2Dstructure containing round pores. The crack is deflected due to the influence of the pores on the strain fieldand might grow into a pore. Furthermore, the initiation of cracks from the pore surfaces is modelled with acombined stress-energy criterion. The model contributes to the understanding of toughening mechanisms inheterogeneous materials. It is capable of showing the influence of the pore content, the pore arrangement andpore shape on the resistance to crack propagation.
