Solid vs Surface - Different results
I simulated a T-joint subjected to a nodally distributed force on its top surface, and fixed at the edge of the web. I simulated the model using both solid elements, and shell elements on the extracted midsurfaces. The stress results are very different. I don't understand why.
The model dimensions are shown below:
The material is set tot he default steel values.
The boundary conditions on the solid model (50 kN nodally distributed. All 6 DOF = 0 on bottom face):
The boundary conditions on the shell model are the same. The PSHELL thickness is set to 20 mm:
The stress results are very different:
What's going on?
