•An introduction to solid body contact will be presented in this chapter:
–It is assumed
that the user has already covered Chapter 2 Nonlinear
Structural prior to this chapter.
•The Specific topics introduced are:
A.Basic concept of contact
B.Contact Formulations
C.Stiffness and Penetration
D.Workshop 3A
E.Pinball Region
F.Symmetric vs. Asymmetric
G.Postprocessing Contact Results
H.Workshop 3B
•The capabilities described in this Chapter
are generally applicable to ANSYS Structural licenses and above.
How compatibility is enforced in a contact region:
•Physical contacting bodies do not
interpenetrate. Therefore, the program
must establish a relationship between the two surfaces to prevent them from
passing through each other in the analysis.
–When the
program prevents interpenetration, we say that it enforces contact compatibility.
–Workbench
Mechanical offers several different contact formulations to enforce compatibility at the contact interface.
