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。
Finite element analysis method was used to study the stress intensity factor of the crack tip after the crack patch adhesive composite patch. The results show that increasing the width and thickness of the patch, or reducing the length of the patch, can improve the repair effect of the structure.
