evaluateMaterial

Optional arguments

Note:

Although uniaxialStrainRange, biaxialStrainRange, planarStrainRange, volumeRatioRange, and simpleShearStrainRange are optional arguments, at least one of them must be specified with a nonzero value.

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.
