摘要
采用有限元分析方法,研究了裂纹板胶接复合材料补片后,裂纹尖端的应力强度因子值。结果表明增加补片的宽度和厚度,或者减小补片的长度,都可以提高结构的修补效果。
Based on the finite element method a numerical investigation into the reduction in the stress intensity factorsSIF at the crack tip of cracked plates bonded with composite patches is presented here in the paper. In general increasing the width and thickness of a patch or reducing its length will improve repair efficiency.
