This study experimentally and numerically investigated the tensile damage progress in stitched CFRP laminate with an open-hole. Detailed damage observation in the tensile tests revealed that stitching had almost no effect on the onset of the ply cracks. Delamination also appeared at the all ply interfaces near the hole, and was connected by neighboring ply cracks. We then performed damage extension simulation for holed stitched-laminate using a layer-wise finite element model with cohesive elements for the damage (ply cracks and delamination) and beam elements as stitch threads. Simulation results confirmed that the delamination extended toward the area surrounded by the ply cracks in the neighboring two layers and the edge of the open-hole. Moreover, we demonstrated that stitching could suppress the delamination progress from the hole edge.
