I agree with you. Something is wrong in the drilling degree of freesom.
However, I don't think that we can solve this issue by setting the rotaion zero.
If the rotation is zero, the translational components of displacment at the point is affected. Please see the definition of the drilling degree of freedom. Actually, the plane stress problem doesn't constrain the rotation. It is totally free.
Yes, I just want to test it plane stress behavior under a inplane load. The out-of-plane response is OK now. |
