*POTENTIAL

Define an anisotropic yield/creep model.

This option is used to define stress ratios for anisotropic yield and creep behavior. It can be used only in conjunction with material models defined by the CREEP option, the CLAY PLASTICITY option, the PLASTIC option (HARDENING=ISOTROPIC, KINEMATIC, or COMBINED; the POTENTIAL option can be used in conjunction with COMBINED hardening only in Abaqus/Explicit), and/or the VISCOUS option.

Optional parameters

DEPENDENCIES

Set this parameter equal to the number of field variable dependencies included in the definition of Rij in addition to temperature. If this parameter is omitted, it is assumed that the anisotropy ratios are constant or depend only on temperature. See Material data definition for more information.

Data lines used to define stress ratios

First line
  1. R11.

  2. R22.

  3. R33.

  4. R12.

  5. R13.

  6. R23.

  7. Temperature.

  8. First field variable.

Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than one)
  1. Second field variable.

  2. Etc., up to eight field variables per line.

Repeat this set of data lines as often as necessary to define the dependence of Rij on temperature and other field variables.
