ProductsAbaqus/StandardAbaqus/ExplicitAbaqus/CAE TypeModel data LevelModel Abaqus/CAEProperty module Hyperelastic material modelVolumetric loading test data can be provided by this option to include user-defined material compressibility. Compressibility can alternatively be included by using the POISSON parameter on the HYPERELASTIC option or, in the case of the Marlow model, by specifying the nominal lateral strain under the UNIAXIAL TEST DATA option. If none of these options is used to specify volumetric behavior, Abaqus/Standard assumes that the material is incompressible, while Abaqus/Explicit will select a default value for the compressibility. See the discussion under “Compressibility” in Hyperelastic behavior of rubberlike materials before using this option in Abaqus/Explicit. Optional parameters
Optional parameter when the VOLUMETRIC TEST DATA option is used in conjunction with the HYPERELASTIC, MARLOW option
Data lines to specify volumetric test data for hyperelasticity other than the Marlow model (the volume ratios must be arranged in either ascending or descending order if the SMOOTH parameter is used)
Data lines to specify volumetric test data for the Marlow model (the volume ratios must be arranged in descending order if the SMOOTH parameter is used)
