Parameters
----------
material
A Material object.
simulationName
A String specifying the name to be used for the material evaluation simulation.
dataSource
A SymbolicConstant specifying whether test data or coefficients should be used for the
material definition in the unit element tests. Possible values are TEST_DATA or
COEFFICIENTS.
strainEnergyPotentials
A sequence of SymbolicConstants specifying for which material models the material is to
be evaluated. Possible values are POLY_N1, POLY_N2, POLY_N3, POLY_N4, POLY_N5, POLY_N6,
OGDEN_N1, OGDEN_N2, OGDEN_N3, OGDEN_N4, OGDEN_N5, OGDEN_N6, REDUCED_POLY_N1,
REDUCED_POLY_N2, REDUCED_POLY_N3, REDUCED_POLY_N4, REDUCED_POLY_N5, REDUCED_POLY_N6,
ARRUDA_BOYCE, VAN_DER_WAALS, YEOH, MOONEY_RIVLIN, and NEO_HOOKE.Note:The options
POLY_N3, POLY_N4, POLY_N5, and POLY_N6 are valid only if the material was defined by
providing coefficients of the strain energy potential.
marlowData
None or a sequence of SymbolicConstants specifying the types of test data to be included
in the material definition of the Marlow material that is being evaluated. Possible
values are UNIAXIAL, BIAXIAL, PLANAR, or VOLUMETRIC. The default value is None.
marlowDataType
None or a SymbolicConstant specifying the input data type for the Marlow material model.
Possible values are TENSION, COMPRESSION, or BOTH.
testDataTypes
A sequence of SymbolicConstants specifying the types of test data to be included in the
material definition of the material being evaluated. Possible values are UNIAXIAL,
BIAXIAL, PLANAR, and VOLUMETRIC.
uniaxialStrainRange
A tuple of Floats specifying minimum and maximum nominal strains to be applied in the
uniaxial tension test.
biaxialStrainRange
A tuple of Floats specifying the minimum and maximum nominal strains to be applied in
the biaxial tension test.
planarStrainRange
A tuple of Floats specifying the minimum and maximum nominal strains to be applied in
the planar test. The planar test is equivalent to a pure shear test.
volumeRatioRange
A tuple of Floats specifying the minimum and maximum compressive volume ratio.
simpleShearStrainRange
A tuple of Floats specifying the minimum and maximum nominal strains to be applied in
the simple shear test.
viscoDataSource
None or a SymbolicConstant specifying whether test data or coefficients should be used
for the viscoelastic material definition in the element tests. Possible values are
TEST_DATA or COEFFICIENTS. The default value is None.
viscoTestDataTypes
None or a sequence of SymbolicConstants specifying the types of test data to be included
in the material definition of the viscoelastic material being evaluated. Possible values
are UNIAXIAL, BIAXIAL, PLANAR, or VOLUMETRIC. The default value is None.
relaxationTime
None or a Float specifying the time period for the stress relaxation response mode. The
default value is None.
creepTime
None or a Float specifying the time period for the creep response mode. The default
value is None.
Raises
------
- If *dataSource*=TEST_DATA and *strainEnergyPotentials* contains POLY_N3, POLY_N4,
POLY_N5, or POLY_N6:
MaterialEvaluationError: POLY_N3, POLY_N4, POLY_N5, or POLY_N6not allowed for
*dataSource*=TEST_DATA.
- If the material evaluation failed:
MaterialEvaluationError: material evaluation failed, see*path to data file*.
- If the material type of the material to be evaluated is not hyperelastic:
MaterialEvaluationError: Material evaluation is currentlysupported only for
hyperelastic materials.
