Products: ABAQUS/Standard ABAQUS/Explicit
The verification tests in this section consist of one-element relaxation tests with viscoelastic materials and involve transferring results between ABAQUS/Standard and ABAQUS/Explicit or from one ABAQUS/Standard analysis to another ABAQUS/Standard analysis. Both small- and finite-strain time domain viscoelasticity with all possible stress states are tested. For finite-strain viscoelasticity the polynomial, Ogden, Marlow, Van der Waals, and Arruda-Boyce forms of strain energy potentials as well as hyperfoams are considered. The elements are loaded in tension or shear followed by relaxation at constant strain. The tests are performed for different combinations of the UPDATE and STATE parameters on the *IMPORT option. The results are transferred at the end of the first step of the original analysis, and relaxation is allowed to continue in the import analysis.
The results demonstrate that the viscoelastic material model is transferred successfully between ABAQUS/Explicit and ABAQUS/Standard and from one ABAQUS/Standard analysis to another. The relaxation behavior of the material after import is consistent with the original analysis, where relaxation is allowed to continue in a second step for the same amount of time as the import analysis.
