如何记录监测点压力大小

zhuxuekaihao

如题，在做应力场分析时，我想获得某一点的应力大小，感觉应该和获得它的位移大小差不多，位移可以用hist id=1 gp zdis 2 40 18来获得，那么应力大小应给用什么呢？我尝试了hist id=1 gp pp 2 46 18，可是为什么没有显示呢？谢谢大神的帮助！

You need to understand the basic definition of stress. Stress is defined as a force over an area therefore you cannot monitor stress for a point. Instead, it can only be monitored in "an finite area" such as an element.
