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).(adsbygoogle = window.adsbygoogle || []).push({});

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.

Alice
