Hi Georgios,

The stress distribution looks file to me. Around the fillets is where we typically see larger stresses. I suppose you used plasticity in the gasket.

By the way, you can specify the diamonds to behave like a "rigid" material since they are much stiffer than the gasket and I assume stresses in the diamonds are not of importance. This will significantly reduce the run-time of the model. Just a suggestion.
