Non-linear quasi-static analysis with contact

 

A gasket (blue) is between two cylindrical tubes and the outer cylinder is subjected to a pressure.

Modeling aspects of this case include:

  • Non linear implicit static analysis
  • Contact modeling
  • Elastoplastic material for gasket
  • Pressure – closure definition of gasket (loading and unloading curves)
  • Gasket elements
