Good Evening,
I recently have been trying to work out the best route to simulate the deflection caused, when you heat a compound bimetallic strip with two materials of different rates of thermal expansion.
The end result is to calculate how long it will takes for the material to recover to its original form once the temperature has been removed.
If you have any thoughts, I would be extremely grateful.
Best regards
Ian C

Dear Ian,
To simulate the deflection of the bimetallic strip you need a structural analysis with thermal expansion. To find the time it takes the strip to return to its original shape you need the time it takes the temperature to nearly reach its original value. For that you need a thermal analysis accounting for all significant modes of heat loss; convection, radiation, and conduction if the strip is connected to anything else.
