GATE ME 2012 | Question: 42
A solid steel cube constrained on all six faces is heated so that the temperature rises uniformly by $\Delta T$. If the thermal coefficient of the material is $\alpha$, Young's modulus is $E$ and the Poisson's ratio is $\upsilon$, the thermal stress developed in the cube due ... $-\dfrac{\alpha (\Delta T) E}{3 (1-2 \upsilon)}$
