Derive the virtual work formula 12.25 for bending of

plates. Note that

1. Use ANSYS, SHELL281, to determine the deflection at

the center for a uniformly loaded square plate with clamped edges for a = b =

20, h = 1, _ = 0.3, D = 100, so that E = 10.92. Use 1/4 of the plate and

symmetry conditions. Submit element layout, maximum deflection, maximum and

minimum values of moments and shears, and plot of QY for the clamped edge y =

0. See Section 15.27.
