beam188单元的剪切应变

[userzff067]

就是我在用apdl创建悬臂梁的时候用的是beam188单元，圆截面，想输出截面的单元剪切应变EXYEXZ，因为beam188是铁木辛柯梁，所以理论上应该是整根杆的这个值都是定值。现在就是每次算出来都是0，剪切应变都是0.已经开了那个KEYOPT(4) = 2，也有剪切应力，但是剪切应力在截面上值是变动的，理论上截面的剪切应力也得是不变的吧？求给出剪切应变如何设置使得它能输出的方法

No, I specify that I must use beam188 elements, and the element used in the example you gave is SHELL281. I want to use beam188 elements to obtain the shear strain of the cross section, which is a constant. It can be easily obtained through theory, but I must use the beam188 element of ANSYS to obtain it

My apologies for the inconvenience. You can try this example: VM2 Input Listing (ansys.com)
