The verification tests in this section consist of one-element models that are subjected to tensile, pure shear, or bending loads in ABAQUS/Explicit. The analyses in ABAQUS/Explicit are followed by analyses in ABAQUS/Standard in which the results are imported from the ABAQUS/Explicit analysis and the loading is removed. Nearly all the tests involve purely elastic materials. The tests are performed for all combinations of the UPDATE and STATE parameters on the *IMPORT option. To verify that the results from the ABAQUS/Explicit analyses are imported correctly into ABAQUS/Standard, the results of the ABAQUS/Standard analyses should show that the elements return to their original configuration before the loading in the ABAQUS/Explicit analysis, except when STATE=NO on the *IMPORT option, in which case the elements remain in the deformed configuration.
The sequence of loading in ABAQUS/Explicit and unloading in ABAQUS/Standard is illustrated in Figure 3.12.11
for an S4R element loaded in tension when UPDATE=YES and STATE=YES.The loading is applied in the ABAQUS/Explicit analyses by prescribing the appropriate displacements. In the ABAQUS/Standard analyses all the boundary conditions must be redefined, and in all cases only the fixed boundary conditions are defined. The shell and membrane elements are loaded so that the maximum displacements are 2. The remaining elements are loaded so that the maximum displacements are 0.2.
Analyses with reduced-integration elements require hourglass control to remove singular (hourglass) modes. However, differences in the hourglass forces computed in ABAQUS/Explicit and ABAQUS/Standard affect the force equilibrium for imported problems. Using enhanced hourglass control for both the ABAQUS/Explicit and ABAQUS/Standard analyses minimizes the differences in the hourglass forces upon import. Verification tests with enhanced hourglass control for both the ABAQUS/Explicit and ABAQUS/Standard analyses are included to test the performance of import problems.
The material model used for all but one of the tests is isotropic linear elasticity. One test consists of a plastic material modeled with Mises plasticity. The material properties used are as follows:
In all the elastic tests that involve tensile loading, shear loading, and bending, the elements return to their original configuration. In some cases tighter controls for the convergence criteria are enforced for the ABAQUS/Standard analyses to obtain more accurate results.
The elastic tests for shell and membrane elements show differences when comparing the section thickness that is computed by ABAQUS/Standard and the original thickness. In ABAQUS/Explicit the changes in shell and membrane thickness are computed using the material Poisson's ratio, while in ABAQUS/Standard the default is to compute the thickness based on the assumption of no volume change. In most practical cases the thickness change during unloading or springback will be small: the differences observed in these tests occur because the material is assumed to remain elastic for very large deformations.

Compatible solid elements and acoustic elements are tied together. The solid elements are constrained on the face that is opposite to the face tied to the acoustic elements. The acoustic elements are subjected to a pressure loading with a sinusoidal amplitude. After import, the analysis is continued as a dynamic analysis in ABAQUS/Standard. Since acoustic elements have no material state, STATE=YES and STATE=NO are equivalent. Since acoustic elements have only pressure degrees of freedom, UPDATE=YES will import the pressure values while UPDATE=NO will set them to zero.
The import analysis is verified by comparing the results from the zero increment of the imported analysis to the last increment of the previous analysis. The results are further verified by continuing the original analysis for a certain period of time after import and checking those results against the imported analysis.

The verification tests in this section are similar to the ones performed in the first section. One-element models are subjected to tensile, pure shear, or bending loads in ABAQUS/Standard. The results of these analyses are then imported into ABAQUS/Explicit, and the loading is removed. Nearly all the tests involve purely elastic materials. The tests are performed for all combinations of the UPDATE and STATE parameters on the *IMPORT option. To verify that the results from the ABAQUS/Standard analyses are imported correctly into ABAQUS/Explicit, the results of the ABAQUS/Explicit analysis should show that the model oscillates about a mean position when STATE=YES. This mean position is the original configuration before the loading in the ABAQUS/Standard analysis.
The loading is applied in the ABAQUS/Standard analyses by prescribing the appropriate displacements. In the ABAQUS/Explicit analyses all the boundary conditions must be redefined, and in all cases only the fixed boundary conditions are defined. All elements are loaded so that the maximum displacements are 0.2.
Verification tests with enhanced hourglass control for both the ABAQUS/Explicit and ABAQUS/Standard analyses are included to test the performance of import problems.
The material model used is the same as the one used in the previous section.
In all cases the stresses are found to be continuous across the respective ABAQUS/Standard and ABAQUS/Explicit analyses when STATE=YES. The displacements, strains, and energy quantities such as the recoverable strain energy are verified to be continuous across the two analyses when UPDATE=NO. At the beginning of the ABAQUS/Explicit analysis the displacements and strains start from zero if UPDATE=YES, whereas the stresses are set to zero if STATE=NO.

Compatible solid elements and acoustic elements are tied together. The solid elements are constrained on the face that is opposite to the face tied to the acoustic elements. The acoustic elements are subjected to a pressure loading with a sinusoidal amplitude. After import, the analysis is continued as a dynamic analysis in ABAQUS/Standard. Since acoustic elements have no material state, STATE=YES and STATE=NO are equivalent. Since acoustic elements have only pressure degrees of freedom, UPDATE=YES will import the pressure values while UPDATE=NO will set them to zero.
The import analysis is verified by comparing the results from the zero increment of the imported analysis to the last increment of the previous analysis. The results are further verified by continuing the original analysis for a certain period of time after import and checking those results against the imported analysis.
