Abstract The failure behavior of composite laminate is correlation with the inner stress state. The failure is usually occurred near the hole for open-hole tension laminate due to the stress concentration at the hole. Therefore, it is necessary to investigate the tensile behavior of composite laminate containing a hole with different ply angles. The finite element model of carbon fiber reinforced composite laminate was built up using ABAQUS commercial software, and the tensile behavior of composite laminate containing a hole with different ply angles was simulated. The effect of ply angles on the stress and stain distribution of the laminate was analyzed. The simulation results show that the 0°/90° ply can relief the stress concentration near the hole and improve the mechanical properties of composite laminate
