The aim of this investigation was to determine the fracture behavior of a particulate reinforced aluminum alloy composite under combined mode I-mode III loading conditions. A modified three point bend specimen was used to carry out these tests. It was found that the mode I loading condition was energetically most favorable. Addition of mode III components to the system seems to increase the amount of redundant work during fracture without affecting the critical fracture criterion.
