*PLANAR TEST DATA
16.11 *PLANAR TEST DATA: Used to provide planar test (or pure shear) data (compression
and/or tension).
This option is used to provide planar test (or pure shear) data. It can be used only in conjunction with the
*HYPERELASTIC option, the *HYPERFOAM option, and the *MULLINS EFFECT option. This type of
test does not define the hyperelastic material constants fully; at the least, uniaxial or biaxial test data should
also be given.
Products: ABAQUS/Standard ABAQUS/Explicit

*HYPERELASTIC
Optional parameter:
SMOOTH
Include this parameter to apply a smoothing filter to the stress-strain data. If the parameter is omitted,
no smoothing is performed.
Set this parameter equal to the number n such that is equal to the total number of
data points in the moving window through which a cubic polynomial is fit using the least-squares
method. n should be larger than 1. The default is SMOOTH=3.
Optional parameter when the *PLANAR TEST DATA option is used in conjunction with the
*HYPERELASTIC, MARLOW option:
DEPENDENCIES
Set this parameter equal to the number of field variable dependencies included in the definition of
the test data. If this parameter is omitted, it is assumed that the test data 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 information.
