摘要: 在有限元ANSYS软件中,建立了结构简化模型,将结构简化成轴对称模型,变换结构尺寸。通过一
系列的命令流计算应力奇异点周围的应力强度因子,然后分析应力强度因子与各结构尺寸的参数之间的关系,并与
J 积分计算所得数值进行比较,结果表明,应用J 积分计算K 栺具有可行性。

Abstract: In the finite element ANSYS software established simplified structure model, simplified the structure into axisymmetric model, alternated the structure size. Using order flow to compute stress intensity factor around the singularity, then analysed the relation between the stress intensity factor and the structure size and compared to the calculation by Jintegral. The results show that the application of J integral calculation KⅠ has feasibility.

Key words: Quick opening closure ,  ANSYS , J integral , stress intensity factor
