Product: Abaqus/CAE
Benefits: You can now define pressure penetration interactions in Abaqus/CAE. This enhancement increases the coverage and ease-of-use of product functionality within Abaqus/CAE.
Description: Abaqus/CAE now provides support for pressure penetrations in the Interaction module, as shown in Figure 11–2. Pressure penetration interactions can be applied only in a planar or axisymmetric model, not in a three-dimensional model.
A pressure penetration interaction allows you to simulate the pressure of a fluid penetrating between two surfaces involved in surface-to-surface contact. The fluid pressure is applied normal to the surfaces. The surfaces are modeled as master and slave contact surfaces in a surface-to-surface contact interaction in an Abaqus/Standard analysis. The bodies forming the joint may both be deformable (as would be the case with threaded connectors) or one may be rigid (as would occur when a soft gasket is used as a seal between stiffer structures).
You specify the points on the master and slave surfaces exposed to the fluid pressure, the magnitude of the fluid pressure, and the critical contact pressure to define pressure penetrations.
