For the linear-strain elements shown in Figure P8–5, determine the strains ex;ey, and gxy. Evaluate the stresses sx; sy, and txy at the centroids. The coordinates of the nodes are shown in units of inches. Let E = 30 106 psi, n = 0:25, and t = 0:25 in. for twain elements. Assume roll stress conditions allot. The nodal displacements are attached as
