摘要
Abstract
In order to study the interlaminar shear performance of hollow integrated sandwich composites,the core structure of composites is simplified as the double rhombus,and then the corre-sponding entity model is established based on the full analysis of pile structure of the hollow integrated sandwich composites. The progressive failure analysis of the finite element method is applied to predict shear performances,stress distribution and failure modes. The results show that the simulation results agree well with the experimental data. The warp shear performances of the hollow integrated sandwich composites are better than its weft shear performances. The main load-bearing components of the titled composites are its piles,and the failure under shearing loads incurs mainly in the root area of the piles.关键词
