Abstract

Simultaneous analysis of buckling resistance and first ply failure behavior for synthetic and vegetable fiber-reinforced composites have been evaluated. The Modified Nelder-Mead Algorithm has been used to find the optimum buckling loads, and the failure criteria are selected to find the failure loads. The highlighted point in the present study is the probability of the first ply failure before the buckling. This may occur especially on vegetable fiber-reinforced composites. The study results show that first ply failure occurred before buckling for various loading cases of the structure.

合成和植物纤维增强复合材料屈曲失效现象的同时分析和优化设计

摘要

已经评估了合成纤维和植物纤维增强复合材料的抗屈曲性和第一层失效行为的同步分析。已使用改进的 Nelder-Mead 算法来寻找最佳屈曲载荷，并选择失效准则来寻找失效载荷。本研究中的重点是屈曲前第一层失效的概率。这尤其可能发生在植物纤维增强复合材料上。研究结果表明，在结构的各种加载情况下，第一层失效发生在屈曲之前。
