adina结果中怎样看的单元的应力,而不是节点应力?

各位大侠,急救,问题如题。

我也在等这个问题。
单元是否存在应力,还是简单的只存在节点应力??

要看变量类型的,引用一下:
Node field: Variables such as displacement, velocity or acceleration that are output at node points and that can be interpolated within elements (using the nodal shape functions).
Element/layer field: Variables such as stresses that are output within elements or element layers and that can be interpolated within elements. These variables are output by the solution program at the integration points.
Node discrete: Variables such as reaction that are output at node points and that cannot be interpolated within elements.
Element local node: Variables such as consistent nodal forces that are output at the element local nodes and that cannot be interpolated within elements.
Element local node field: Variables such as shell thicknesses that are output at the element local nodes and that can be interpolated within elements.

最后,AUI既可以从单元积分点将结果外推到单元内其他点,也可以把某些单元类型的结果光顺到周围节点。

一个钢管桩插入岩石里,钢管桩用shell模拟,岩石用solid模拟,把岩石和钢管桩的单元节点合并,给桩一个很大的力,这样的话桩就会才产生可能达到200Mpa的应力,但是岩石早就破坏了,这个时候由于岩石的节点和桩的节点是同一个节点,怎样才能把两者的应力分开。

节点上的应力都是由积分点得到的,你可以在后处理Definitions/result grid里设置从单元里读取结果

尝试一下,谢谢
