Static Analysis of Models with Contact Interfaces
Use a static analysis with contact interfaces to model surfaces or components that may either separate from each other or move into contact with each other. They do not interpenetrate each other during the analysis.
For details, see the
description of and
requirements for contact analyses.
For an analysis of a model with contact interfaces, select the following items on the Static Analysis Definition dialog box:
• Nonlinear / use load histories—The Nonlinear / use load histories check box is selected by default. Contacts is highlighted in the Nonlinear options area of the dialog box.
The static analysis with contacts may contain contact regions with frictionless contact and contact regions with
infinite friction.
Calculate large deformations—Select Calculate large deformations to run a large deformation static analysis with contacts.
• Constraints—Allows you to select one or more constraint sets. Enforced displacements in spherical and cylindrical coordinate systems are not supported for a static analysis with contacts.
• Loads—Allows you to select one or more load sets. You must have at least one load set or a constraint set with an enforced displacement.
You must also select items on the following tabs on the Static Analysis Definition dialog box:
For models with temperature-dependent material properties you must specify the model temperature by defining structural temperature loads or MEC/T loads wherever temperature-dependent materials are assigned. Include the load sets that contain these temperature loads in the analysis.
