- The block of material is subjected to a compressive stress z=75MPa Assume there is no friction at the die wall and the material to be isotropic with linear-elastic behavior - For a temperature increase/decrease, how would you expect the value of y to qualitatively change? - Calculate the temperature change that would cause the copper alloy block to be on the verge of losing contact with the walls in the y direction - =16.51061/C,E=130GPa,v=0.343
