I've already read the blog you suggested before. But I did not understand the coefficient of thermal expansion. The coefficient of thermal expansion depends on the temperature, right? Let's say I've already put the coefficient of thermal expansion for temperature 23C which is 0.000165 /C, can I use the same coefficient value for temperature 20C? Let's say my reference temperature is 23C and I want to observe the deformation at a temperature of 20C and -35C.
