TENSILE FAILURE: Specify a tensile failure model and criterion .
This option is used with t he Mises or the Johnson-Cook plasticity models or the equation of state model
to specify a tensile failure model and criterion. It must be used in conjunction with the
*
PLASTIC,
HARDENING=ISOTROPIC option; the
*
PLASTIC, HARDENING=JOHNSON C OOK option; or the
*
EOS option.

Optional parameters:
DEPENDENCIES
Set this parameter equal to the number of field variable dependencies included in the definition of
the hydrostatic cutoff stress, in addition to temperatur e. If this parameter is omitted, it is assumed
that the hydrostatic cutoff stress is constant or depends only on temperature. See “Using the
DEPENDENCIES parameter to define field variable dependence” in “Material data definition,”
Section 16.1.2 of the A BAQU S Analysis User’s Manual, for more information.
ELEMENT DELETION
Set ELEMENT DELETION=YES (default) to a llow element deletion when the failure criterion is
met.
Set ELEMENT DELETION=NO to allow BRITTLE/DUCTILE-type failure for the deviatoric
and hydrostatic parts of stresses.
Required parameters for use with ELEMENT DELETION=NO:
PRESSURE
Set PRESSURE=BRITTLE to model the case where the pressure stress is required to be
compressive when the failure criterion is met.
