Gasket Material Under Uniaxial Compression Loading - 3D
Analysis
Test Case
A thin interface layer of thickness t is defined between two
blocks of length l, width W, and height H placed on top of each other.
The blocks are constrained on the left, bottom, and back faces and
loaded with pressure P on the top face. Determine the pressure-closure
response for gasket elements.
Analysis Assumptions and Modeling Notes
A 3D analysis is performed first using 4 x 4 INTER195 gasket elements and then using 4 x 4 INTER194 gasket elements. In order to simulate the loading-unloading behavior
of gasket material, the model is first loaded with a pressure P1 and
unloaded and then loaded with a pressure P2 and unloaded. The pressure-closure
responses simulated are compared to the material definition.
