Post-buckling reliability analysis of stiffened composite panels based on adaptive iterative sampling

The use of an adaptive iterative sampling method is proposed to analyze the post-buckling reliability of stiffened composite panel structures. First, a post-buckling yield strength model for a stiffened composite panel is established based on a semi-empirical equation, and its accuracy is experimentally verified. On this basis, a reliability analysis model is proposed for a stiffened composite panel. The probability of post-buckling failure is...
