1. ## Thermal expansion material stiffness

Hi I am doing some test calculations in optistruct. I have a very thin plate with basically no mechanical strength and stiffness, attached to a plate with moderate strength and stiffness. When I heat up both plates I get deformations due to thermal expansion which are expected. Now when I only heat up the very thin plate, the deformations due to thermal expansion are higher compared to the previous case (so also the thick plate now has higher deformations even if it is not thermally expanding). This made me wonder the following: is material stiffness is neglected in a thermal expansion analysis?
2. ## Geometric non linear analysis - temperature

Hi, I'm modeling a stiffened sphere subjected to external pressure and to expansion due to high temperature. I performed a geometric non linear simulation considering only the external pressure and now I'd like to evaluate the effect of the high temperature. How can I include it in the analysis? I can't find nothing similar to the TEMP entry of the linear static Thanks, Enrico
