Abstract基于高等弹性力学中的椭球理论,建立远场三轴应力作用下"三个半轴变化的椭球形空洞"的3维模型,得到椭球形空洞洞壁上应力状态的解析式。借助Matlab编程实现了椭球洞壁上应力状态的精确和快速计算,然后在一般椭球洞、旋转椭球洞与球洞的情况下将本文推导出的结果与现有中外文献上的结果作对比分析,最后把利用有限元软件MIDAS分析得出的三个半轴变化的椭球洞壁上关键点的应力状态与运用本文理论得出的结果作对比分析。
Other AbstractAccording to the theory of ellipsoidal cavity in advanced theory of elasticity,the exact stress formulas on the surface of general ellipsoidal cavity(different three semi-axes) in infinite body subjected to triaxial compressive stresses in the directions of three axes of the cavity are obtained.The exact stress solutions on the surface of ellipsoidal cavity are solved accurately and quickly by Matlab software.Then,comparing the results derived in this paper with the result given in existing Chinese-foreign literature under the condition of general ellipsoidal cavity,rotating ellipsoidal cavity and hole.Finally,the results derived in this paper are compared with the result using finite element software "MIDAS" under the condition of general ellipsoidal cavity.
