The tensile failure options enable you to control element deletion for plastic
material behaviors.
Input Data
Description
Use temperature-dependent
data
Specify material parameters that depend on
temperature. A
Temperature field appears in the data table.
Hydrostatic Cutoff Stress
The hydrostatic cutoff stress in terms of
pressure.
Remove failed elements
Select this option to remove elements when the
failure criterion is met.
For failed elements
options
If
Remove failed elements is clear, the failure
criteria are determined using the pressure stress and deviatoric stress
components that you select. There are four failure combinations, described in
the image below:
Ductile shear and ductile pressure (point 1 in the image):
models the case in which the deviatoric stress components are unaffected and
the pressure stress is limited by the hydrostatic cutoff stress,
Brittle shear and ductile pressure (point 2 in the image):
models the case in which the deviatoric stress components are set to zero and
remain zero for the rest of the calculation, and the pressure stress is limited
by the hydrostatic cutoff stress,
Brittle shear and brittle pressure (point 3 in the image):
models the case in which the deviatoric stress components are set to zero and
remain zero for the rest of the calculation, and the pressure stress is
required to be compressive,
Ductile shear and brittle pressure (point 4 in the image):
models the case in which the deviatoric stress components are unaffected and
the pressure stress is limited by the hydrostatic cutoff stress,
