Problem Description
In this example a rectangular plate with irregularly shaped elements is subjected to prescribed displacements at the edges that theoretically impose a constant stress field over the model. The geometry, properties and loading are as described in MacNeal and Harder 1985. The membrane and plate bending stress components resulting from the prescribed displacements are compared with hand calculated results. Joints 1, 2, 7 and 8 are restrained for translation in the X, Y and Z directions and for rotation about the X and Y axes. No joint restraint is specified about the Z axis. The prescribed displacements are applied to the restrained degrees of freedom of those joints. The shell section is modeled using full shell behavior; that is, both membrane and plate bending behavior. Separate models are used to test the thin-plate and thick-plate options. Because the model is flat, that is, all in one plane, there is no coupling between the membrane and the plate bending behavior.
