block made of an elastic material with Young's modulus of 200GPa and Poisson's ratio of 0.2 should be fitted between two rigid fixtures. The gap between the two fixtures is 0.47 m and the undeformed dimensions of the elastic material that should be fitted between the fixtures is 0.5mx5mx5m. 1 1 ij E ij kk ij ; ij 1 ij 1 2 kk ij E a) what is the minimum compressive force that should be applied to the elastic block in order to fit it between the rigid fixtures? b) After the block is fitted between the fixtures, the top and bottom surfaces will be welded to the fixture. Then, a horizontal displacement of 10mm is applied to the top fixture. Determine the strain and stress tensors in the elastic block
