摘要
本文是文献［１］的继续．文献［１］利用可动边界变分问题，导出了层合板内部脱层前缘各点处的总能量释放率的表达式．在此基础上，本文对文献［１］的分析模型作了进一步的完善．导出了尾板理论分析下的能量释放率各型分量的表达式，并对圆形脱层进行了计算分析．
This Paper is the continuation of the authorl's previous paper in which the formula of total energy release rate at each point along the delalnination front was derived by using variational method of moving boundary. In this paper, the analytical model is reformed and the formulas of individual components of energy release rate are derived in the form of plate theory.The circular delaminations embeded in circular laminates are analysed.
