Dear all, I am trying to calculate the stresses and strains induced by a 40K change in temperature of a steel sheet of thickness 5mm, that is clad on both sides with 2mm thick layers of copper. For both materials E, alpha (í.e. the thermal expansion coefficient), as well as v (Poissons ratio are given).

My attempt was equating the forces (see attached word document).

This does unfortunately not work and the fact that the Poisson ratios are given makes me think that I have missed something out. Can anyone help?

Thanks a million for any help, hints and suggestions.
