Set this parameter equal to the number of viscoelastic networks in the model.
Optional parameters
DEPENDENCIES
Set this parameter equal to the number of field variable dependencies included in the definition of the stiffness ratios, in addition to temperature. If this parameter is omitted, the hardening behavior does not depend on field variables. See Material Data Definition for more information.
Data lines to define the stiffness ratio if N=1
First line
Stiffness ratio for the viscoelastic network 1, .
Temperature.
First field variable.
Etc., up to eight entries per line.
Subsequent lines (only needed if the number of entries is greater than eight)
Seventh field variable.
Etc., up to eight entries per line.
Repeat this set of data lines as often as necessary to define the dependence of the stiffness ratios on temperature and other predefined field variables.
Data lines to define the stiffness ratio if N=2
First line
Stiffness ratio for the viscoelastic network 1, .
Stiffness ratio for the viscoelastic network 2, .
Temperature.
First field variable.
Etc., up to eight entries per line.
Subsequent lines (only needed if the number of entries is greater than eight)
Sixth field variable.
Etc., up to eight entries per line.
Repeat this set of data lines as often as necessary to define the dependence of the stiffness ratios on temperature and other predefined field variables.
Data lines to define the stiffness ratio for higher values of N
Data lines
The data lines for higher values of N follow the same pattern. First, give for i from 1 to N. Then, give the temperature. Finally, give the values of the field variables. Exactly eight data values should be given on each line.
