Dear Ansys Community,
I am conducting a thermo-mechanical simulation on the attached model below. For the stress analysis due to thermal loading, I need to apply support at the bottom surface, such that no stress is being developed there due to the support. Because in the oven we just place the specimen and not fix it. So please help me how to apply the BC.
1. applying remote displacement on to the edge of the bottom surface fixing in all DOF. But that works only for a single thermal cycle. If more cycles of thermal cycle exists, stress concentrates on the edge and unlikely deformation is being seen.
2. I also tried the combination of remote displacement on edge and frictionless support on face. But still unlikely deformation is happening.
Please help me how to fix this issue ie, how to give boundary conditions at the bottom without stress concentration at the fixed region.
Thanks in advance
