Hello,
I am having a problem with a simple 2D model: I submit a square plate with an expansion coefficient alpha=10^-6 to a uniform temperature T=50. I use only a ENCASTRE boundary condition on one corner. When I ask Abaqus for strain, it gives me E11=E22=70*10^-6. I was expecting it to be alpha*T=50*10^-6. ABAQUS says that my thermal strain ETH is 50*10^-6 but it says that there is also an elastic strain EE=20*10^-6
Does anyone have an idea to explain this result? Where does EE come from?
Thank you in advance
Paul
