Features tested

The submodeling capability is applied to gasket elements. The general static procedure is used for both the global and submodel analyses.

Problem description

Model:

All global models consist of a rectangular gasket, with a length of 3 and a thickness of 0.125. The three-dimensional models have a width of 1. The submodel input files model the right half of the global model. All nodes on the submodel are driven.

Material:

Membrane elastic modulus	68.7 × 10³
Transverse shear stiffness	1.06 × 10⁴
Poisson's ratio	0.3
Thickness behavior	Pressure of 2.75 × 10⁴ at a closure of 1

Loading and boundary conditions:

The gasket is loaded through contact with two rigid surfaces. The lower rigid surface is held fixed. The upper rigid surface is moved down and rotated to impart a spatially varying stress response in the gasket. Additional boundary conditions are applied to the gasket to suppress rigid body motion.
