Product: ABAQUS/CAE
Benefits: You can now evaluate the Marlow strain energy potential for hyperelastic materials; you can also evaluate viscoelastic materials.
Description: Material evaluations can now be performed for hyperelastic materials that are defined with a Marlow strain energy potential. The Poisson's ratio—previously available in ABAQUS/CAE for use only with the Marlow model—can now be used to calculate the volumetric response for all of the hyperelastic strain energy potentials. You can now also evaluate the creep and relaxation response of viscoelastic materials, provided that the material definition also includes elastic or hyperelastic material data.
In addition, the material editor for viscoelastic materials has been updated. Like the hyperelastic material editor, the test data options (combined, shear, and volumetric) have been moved to a Test Data menu. The TRS coefficients remain in the Suboptions menu.
