My company had just bought a premium version a month before. As I am not so familar on using the simulation module, I would like to ask for some suggestions.
Currently, I am doing a project on caculating the thermal stress of a bi-metallic strip under cooling. From the training manual, I know roughly how to do it: just do a steady state thermal simulation first, and that attach a thermal load during the static part.
But I have some questions that I make me don't know how to handle the case:
1) If the materials of my bi-metallic strip has a temperature dependent factor, how should I handle to run the solution? Currently, the thermal expansion coefficient (CTE) of my material will be vary from time to time during the cooling process. And I think this will affect the utimate thermal stress stored in the components. So how can I make the settings/ what can I do so that the simulation program could calculate the effect? (Note: I know how to set / import a temperature dependent curve, but I don't know how to set the software to handle the data)
2) In my case, I think how fast I cooling would affect the magnitude of residual stress. So, how can I use the simulation to handle the effect of cooling rate/ convection coefficient?
Looking forwards for your recommendation,
