Determine the nodal displacements and the element stresses,
including principal stresses, due to the loads shown for the thin plates in
Figure P6–14 on the next page. Use E = 210 GPa, n = 0:30, and t = 5 mm. Assume
plane stress conditions apply. The recommended discretized plates are shown in
the figures.
