FrictionMM Command

This command has been deprecated. You should set multimaterial mode friction properties using a ContactMM command instead.

The FrictionMM command sets the default contact for multimaterial mode MPM calculations to use frictional contact::

FrictionMM (frict)

where (frict) will result in automatic creation and use of a frictional contact law for multimaterial contact:

Notes

  1. The FrictionMM command sets the frictional properties for all material contact. In simulations with more than two materials, you might want different friction between different pairs of materials. To implement such custom contact, use the Contact material property (or a deprecated Friction commands within material definitions).
  2. Frictional energy from material contact can optionally be converted into heat when running conduction calculations.
  3. The FrictionMM command is only allowed for MPM analyses.
