摘要
提出了一种合理、简便、精确的修正的剪滞模型· 基于此模型 ,分析了受拉伸的层内混杂复合材料中某些纤维断裂后的应力重分布· 结果表明 ,求得的应力集中因子与Fukuda和Chou的结果相当接近 ,从而证实了本文模型和方法的合理性和正确性·
A reasonably, simply and accurately modified shear_lag model was proposed. Based on the model, the stress redistributions due to the failure of some fibers in an intraply hybrid composite under tension were analyzed. The results show that the present calculating stress concentration factors very coincide with Fukuda and Chou's results, thus verifying the reasonableness and correctness of the present model and methods.
