Optional parameters

DEPENDENCIES: Set this parameter equal to the number of field variable dependencies, in addition to temperature, that define the normal distribution of the nucleation strain. If this parameter is omitted, the constants defining the normal distribution may depend only on temperature. See Material data definition for more information.

Data lines to define void nucleation

First line

$ε_{N}$ , mean value of the nucleation-strain normal distribution.
$s_{N}$ , standard deviation of the nucleation-strain normal distribution.
$f_{N}$ , volume fraction of nucleating voids.
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 $ε_{N}$ , $s_{N}$ , and $f_{N}$ on temperature and other predefined field variables.
