PLANAR TEST DATA

*
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
Type: Model data
Level: Model

HYPERELASTIC
Optional parameter:
SMOOTH
Include this parameter to apply a smoothing filter to the stress-strain data. If the parame ter is omitted,
no smoothing is performed.
Set this parameter equal to the num ber n such that
is equal to the total number of
data points in the moving window through which a cubic polynom ial 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 tha t 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.
