CrackThickness Command

The CrackThickness command sets the thickness for an explicit crack. It is only needed if the crack has any particles with a traction law or when crack tips release their energy into heat.

CrackThickness (thick)

where (thick) is the thickness of the crack in length units.

Notes

  1. The CrackThickness command must come after the first NewCrack command. Once a CrackThickness command has been used, all subsequent cracks will use the same thickness unless a new CrackThickness command changes it.
  2. If the grid was created using a GridThickness command, the crack thickness will inherit that thickness. You only need a CrackThickness command to have a different thickness (although having a different thickness is very uncommon and may alter the physics of the cracks.)
  3. The CrackThickness command is only allowed for MPM analyses.
