stress-relieving cavity

Nonlocal measurement of stress concentration in an elastic body with a spherical cavity

含球形空穴弹性体中应力集中的非局部度量

According to the wall testing process, we put finite element numerical simulation on the cavity wall which is set the ring beam but without structural concrete column, using discrete model to analysis the principal stress, cracks distribution and displacement of the wall.

参照墙体试验过程，对设置圈梁但无混凝土构造柱的空斗墙体进行有限元数值模拟，采用分离式模型对墙体的主应力、裂缝分布与墙顶位移变化进行分析。

Numerical modeling analysis of the construction method with several layers excavating and stress discharging in advance for large underground cavity

大型地下洞室多层耦合应力超前解除法施工数值模拟

Dynamic stress concentration around an interface cavity of arbitrary shape by SH waves

SH波作用下界面任意形状孔洞附近的动应力集中

These thoughts can be applied to cylindrical voids. Subsequently, the paper solves two common problems: axisymmetric plane-stress problem and spherical cavity expansion problem.

可以把这些思想应用于柱球形胞元等问题的细观分析中。论文分析了两种工程常见的力学问题：轴对称平面应力问题和球形孔洞膨胀问题。
