*CRUSH STRESS VELOCITY FACTOR

Define how the approach velocity at a crushing interface influences a material's resistance to crushing.

The option is used, if necessary, to define how the approach velocity at a crushing interface influences a material's resistance to crushing. It must be used as a suboption of the CRUSH STRESS option. Abaqus/Explicit uses a regularization scheme for the evaluation of the crush stress scaling factor as a function of relative velocity.

The CZone for Abaqus algorithm requires that the scaling factor be the same for all plies in a composite laminate. Therefore, identical CRUSH STRESS VELOCITY FACTOR definitions must be used in all materials referenced by the same composite shell section definition.

Data lines to define velocity-dependent crush factors

First line
  1. Scaling factor to be applied to the crush stress.
  2. Relative velocity between the two surfaces.

Repeat this data line as often as necessary to define the crush stress scaling factor as a function of relative velocity.
