*POTENTIAL
16.22 *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 *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 parameter:
DEPENDENCIES
Set this parameter equal to the number of field variable dependencies included in the definition
of
in addition to temperature. If this parameter is omitted, it is assumed that the anisotropy
ratios are constant or depend only on temperature. See “Specifying field variable dependence”
in “Material data definition,” Section 16.1.2 of the ABAQUS Analysis User’s Manual, for more
