Solve these problems using the plate element from a computer program.

A square steel plate (Figure P12–1) of dimensions 20 in. × 20 in. with thickness of 0.1 is clamped all around. The plate is subjected to a uniformly distributed loading

of 1 lb/in². Using a 2 × 2 mesh and then a 4 × 4 mesh, determine the maximum deflection and maximum stress in the plate. Compare the finite element solution to the classical one in [1].
