change of inner stress的意思|示意

In this paper, by the means of theory and numerical simulation, the change of inner stress of high building during its collapse by blasting is calculated.

采用理论分析与数值计算的方法对高耸建筑物爆破拆除中建筑物倾倒过程中的内力进行了分析计算，得到了内力的演化规律。

The results show that the stress concentration is in the pointed Angle of composed face of rubber sealing X-ring change section, mainly in inner pointed Angle that it is easy to break.

结果显示：X形变截面密封圈的应力集中部位主要集中在组合面尖角处，特别是内尖角处更易损坏。
