加劲空心圆柱的径向裂纹分析^*

基金项目: * 中国科学院科学基金资助的课题

摘要: 本文结合使用Michell环形域级数解及单裂纹解,导出了外边界被加劲的空心圆柱的径向裂纹积分方程,进而分析了加劲薄膜对裂纹应力强度因子的影响。文中给出了若干数值计算结果。

Abstract: Using the Michell solution and the crack solution, the integral equation of a radial crack in a hollow cylinder reinfcreed on its outer boundary is derived. The effects of the reinforced membrane on the crack are analysed and several numerical results arc presented herein.
