Question:

For the plane stress plate fixed along all edges and subjected to a uniform temperature decrease of 20°C as shown in Figure P15 -18, determine the stresses in each element. Let E = 210 GPa, v = 0.25, and Î± = 12 Ã— 10-6 (mm/mm)/°C. The coordinates of the plate are shown in the figure. The plate thickness is 10 mm.
