Using a computer program, solve the following problems.

The square plate in Figure P15–23 has element 1 made of steel with E = 30 × 10⁶ psi, v = 0:33, and a = 10 × 10^–⁶/ ° F and element 2 made of a material with E = 15 × 10⁶psi, v = 0:25, and a = 50 × 10^–⁶/ ° F. Let the plate thickness be t = 0:1 in. Determine the nodal displacements and element stresses for element 1 subjected to an 80 ° F temperature increase and element 2 subjected to a 50 ° F temperature increase.
