Other Capabilities

Many other postprocessing functions are available in POST1. See The General Postprocessor (POST1) in
the Basic Analysis Guide for details. Load case combinations usually are not valid for nonlinear analyses.

10.7.3. Reviewing Results in POST26.

You can also review the load-history response of a nonlinear structure using POST26, the time-history
postprocessor. Use POST26 to compare one ANSYS variable against another. For instance, you might
graph the gasket closure vs. gasket pressure, which should correspond to the material behavior defined
by TB,GASKET. You might also graph the displacement at a node versus the corresponding level of
applied load, or you might list the gasket pressure at a node and the corresponding TIME value. A
typical POST26 postprocessing sequence for a gasket analysis is the same as the sequence for a typical
nonlinear analysis. See steps 1 through 4 in Reviewing Results in POST26 (p. 253) included in Nonlinear
Structural Analysis (p. 193).

10.8. Sample Gasket Element Verification Analysis (Command or Bat ch Method)

This is a simple finite element model created to demonstrat e the gasket material simulation. Two block
elements with element type SOLID185 were generat ed as supporters and a gasket element INTER195
was created. The whole system is fixed along one side of each axes to prevent rigid body motion. A
prescribed displacement is placed on top of the supporter element. The gasket material is assumed to
have a nonlinear compression behavior with 5 different linear unloading slopes. A pressure stress cap
of 1.0e-5 is imposed so that no tension stress is generated. Two load steps were used.

The ANSYS commands are shown below.
