Question

Now we go back to our three-dimensional constitutive law. Consider an isotropic cube with our typical material properties that has been buried in a rigid matrix so that it cannot move. The temperature is increased by an amount AT. Show that the normal stress (on each face, but you only have to do one) is equal to-EaAT/(1-2u). This is actually a very short problem but the key assumption here is that the normal stresses on each of the three faces will all be the same value Also note that when the Poisson ratio is zero, our result is exactly the same that we found for the railroad tie problem when we first studied thermal effects. 3.
