Membrane submodeling

The submodeling capability is applied to membrane models. The global input files use the models from the membrane patch tests described in Membrane patch test. The submodel input files model the right half of the global model; in Abaqus/Standard the submodel has 16 M3D8 elements, and in Abaqus/Explicit the submodel uses 16 M3D4R or 32 M3D3 elements. The submodel driven nodes lie along the line parallel to the y-axis of the model. In Abaqus/Standard static perturbation and static general procedures are tested. In Abaqus/Explicit the analysis is performed as a quasi-static procedure; a velocity boundary condition that gives rise to the perturbation is specified instead of the perturbation step.
