PLANAR TEST DATA
Data lines to specify planar test data for hyperelasticity other than the Marlow model:
First line:
1. Nominal stress, .
2. Nominal strain in the direction of loading,
.
Repeat this data line as often as necess ary to give the stress-strain data.
Data lines to specify planar test data for the Marlow model:
First line:
1. Nominal stress, .
2. Nominal strain,
.
3. Nominal lateral strain,
. Not needed if the POISSON parameter is specified on the
*
HYPERELASTIC option or if the
*
VOLUMETRIC TEST DATA option is u sed.
4. Temperature,
.
5. First field variable.
6. Second field variable.
7. Etc., up to four field variables.
Subsequent lines (only neede d if the DEPENDENCIES parameter has a value greater than four):
1. Fifth field variable.
2. Etc., up to eight field variables per line.
Repeat this set of data lines as often as necessary to define the test data as a function of temperature
and other predefined field variables. Nominal strains and nominal stresses must be given in asce nding
order.
