ContactCracks Command

The ContactCracks command is used to set the contact conditions for crack surfaces:

ContactCracks (lawid)

where

The ContactCracks command defines the default contact law properties for explicit crack surface contact. Any specfic crack can optionally specifiy a different contact law when it is defined with a NewCrack command.

Notes

  1. Frictional energy on crack surfaces can optionally be converted into heat when running conduction calculations.
  2. The ContactCracks command is only allowed for MPM analyses.
