Abstract The development and aggregation of composite damage, is one of the important reason to cause composite structure failure. In this paper, the nonlinear analysis model was established based on the composite progressive damage analysis method. The research effort focused on composite strength failure criterions and numerical simulation of damage evolution laws. Combined with the finite element analysis method, the constitutive relations containing damage was derived. The composite structure failure modes and ultimate bearing capacity of the plate with hole, I-plate and rudder shaft structures were studied under different types of load by ANSYS. Finally, the validity of the numerical simulation was approved by experiments. Results show that the nonlinear progressive damage model can precisely predict the damage development of composite structure, additionally, engineering practical application value of this analytical method has been proved.
