UNIAXIAL TEST DATA

*
UNIAXIAL TEST DATA: Used to provide uniaxial test data (compression and/or
tension).
This option is used to provide uniaxial test data. It can be used only in conjunction with the
*
HYPERELASTIC
option, the
*
HYPERFOAM option, and the
*
MULLINS EFFECT option.
Products: ABAQUS/Standard ABAQUS/Explicit
Type: Model data
Level: Model
Using uniaxial test data to define a hyperelastic material

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
*
UNIAXIAL 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.
Data lines to specify uniaxial test data for hyperelasticity other than t he Marlow model:
First line:
1. Nominal stress, .
2. Nominal strain,
.
Repeat this data line as often as necessary to give the stress-strain data.
