*ISOTROPIZATION PARAMETERS

Optional parameters

DEPENDENCIES: Set this parameter equal to the number of field variables, in addition to temperature, on which the isotropization parameters depend. If this parameter is omitted, it is assumed that the isotropization parameters are constant or depend only on temperature.

Data lines to define isotropization parameters

First line

$k_{p}$ , plastic strain multiplier. The default value is 1.0.
$k_{s}$ , plastic strain shift. The default value is 0.0.
$k_{G}$ , shear multiplier. The default value is 1.0.
Temperature.
First field variable.
Second field variable.
Etc., up to four field variables.

Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than four)

Fifth field variable.
Etc., up to eight field variables per line.

Repeat this set of data lines as often as necessary to define the dependence of $k_{p}$ , $k_{s}$ , and $k_{G}$ on temperature and other predefined field variables.
