Principle Stresses are given by
Problem No-3: The coordinates are shown in units of inches. Assume plane stress conditions. Let E...
(0, 2) (4,2) (Coordinates in inch units) (4,0) (0, 0) 3. (5 point) For the element shown in Figure above (Problem 2), determine the stress matrix at s = 0.5773, t = 0.5773 using isoparametric formulation. The nodal displacements are given as Uj = 0) Vj = 0 U2 = 0.005 in. v2 = 0.0025 in. Uz = 0.0025 in. v3 = -0.0025 in. U4 = 0 04 = 0
