<p> I'm trying to simulate a picture frame shear test using ABAQUS and I have landed up with some problems for which I haven't been able to find any solution from almost a week. Any help would be much appreciated!</p>
<p>So, here's the problem:</p>
<p>I have a fabric sheet of area 140mm x 140mm. The BC are as shown in the file bc.png.The bottom left corner is fixed and a displacement of UX = 40mm and UY = 40mm is applied on the top right corner node.</p>
<p>I have to perform the picture frame shear test such that the edges of this square surface remain straight even after deformation. For this purpose, I decided to use MPC Constraints (link) after going through the help documentation. I got the following problem at the corner slave nodes: </p>
<p>2 nodes are missing degree of freedoms. The MPC/Equation/kinematic coupling constraints can not be formed. <span>The nodes have been identified in node set ErrNodeMissingDofConstrDef.</span><span> </span></p>
<p>I have attached an image showing the MPC Constraints along with the master nodes.</p>
<p>I realized that the error was caused because these nodes had two master nodes assigned to them and hence the DOF conflict occurred. In order to overcome this problem, I tried to create a wireframe from the reference point (fixed point) but even that didn't help. The corner elements are still getting deformed along the outer edge and I am not able to find a solution for the same.</p>
<p>Any input to solve this problem would be much appreciated.</p>
<p>Thanks in advance! </p>
