Reliability and sensitivity analysis of edgewise compressive strength for plain woven faceplate honeycomb sandwich structure

doi:10.19936/j.cnki.2096-8000.20221228.002

Abstract

Abstract: For plain woven faceplate honeycomb sandwich structure, the progressive damage failure analysis model is established to study the influence of the randomness of parameters on the lateral compressive strength. Firstly, the output responses corresponding to random input samples are obtained by the use of finite element analysis, and the surrogate model is established by Kriging method. The reliability analysis method based on Monte Carlo is applied for structural reliability analysis, and the sensitivity analysis methods based on variance and failure probability is respectively used for structural sensitivity analysis. The structural reliability index, the sensitivity index of the mechanical properties and thickness are computed, which provides a basis for the structural reliability optimization design.
