Abstract |
|
This article studies progressive failure and ultimate strength prediction of sandwich composite hat-stringer-stiffened panels subjected to the transverse in-plane loads. By using the finite element software ABAQUS and the nonlinear finite element method, a failure criterion and a rigid degradation mode of interwoven fibers have been found, a set of finite element analysis methods for predicting the ultimate strength of sandwich composite hat-stringer-stiffened panels has been established. It has been verified the better accuracy of this method in predicting the ultimate strength and mechanical properties of sandwich composite hat-stringer-stiffened panels by comparing with the experimental results. Finally, the paper analyzes some factors affecting the numerical simulation of progressive failure and ultimate strength and discusses how to improve the accuracy of predicting the behavior of sandwich composite hat-stringer-stiffened panels. |
