摘要
本文讨论了应力状态类型与孔洞变形类型间的关系,推导了等静压对空洞压实的影响表达式,并得出仅靠等静压不能压实孔洞的结论。利用上限原理对孔洞压实过程进行了模拟并和试验作了比较,从而验证了上述结论的正确性。
The relationship between stress state and hole deformation is analyzed. The formulae for closing hole by applying equal compression pressure are deduced. The results confirm that the hole can not be closed by the pressure only. According to the upper limit principle, the process simulation for closing hole has been done, and the results are compared with the experiments.
