Abaqus CAE Standard

[stonehentsch]

Greetings,

My model as seen in the attached file shows two plate which lay on top of each other. the lower one is encastred and the second is supposed to move 10 units in X direction and 10 units in Z direction while rotating 40 degrees. Which is not a problem at all. I want to apply a kinematic coupling constraint which denies the upper plate to move in x direction but it is still allowed to rotate arround the y axis. The problem is that abaqus overrides the coupling constraints of the surface of the upper plate because of the boundary constraints ( moving 10 in x and 10 in z direction. Any suggestions

Thanks in advance

Please try again to attach the file, it’s not present in the post.

So you want to constrain the plate’s motion in X direction in one step and then prescribe displacement in this direction in the following step ? You should apply all BCs in consistent manner - directly or via kinematic coupling. Avoid using both methods at the same time. Also remember that you should modify or deactivate BCs that are not needed or should change in specific step. You can use Boundary Condition Manager for this purpose.
