    Axisymmetric stress analysis with rigid surface, stress distribution seems strange

    Hi corus, thanks for the reply! If I understand correctly, mesh refinement would give me a more correct stress distribution, but the stresses will tend towards infinity unless I include plasticity or large deformations into the model. I will give it a shot with a refined mesh and an...

    Axisymmetric stress analysis with rigid surface, stress distribution seems strange

    Hi all, I run an axisymmetric analysis of a part that comes into contact with a rigid surface and is then loaded with pressure from the inside. My analysis is linear elastic and I use quadratic elements. The analysis steps are: - Use BCs to fix the part in space and move the rigid surface...
