The verification tests outlined in this section are carried out for each element type listed. The finite element model consists of two elements subjected to increasing tensile loads. The first analysis consists of two *STATIC steps. During the first step one element is subjected to half the load that is applied to the other element. During the second step both elements are subjected to the same final loads. The results from the end of the first step of this analysis are transferred to a second analysis where the same loads as in the second step of the first analysis are applied to the two elements. The tests are performed for all combinations of the UPDATE and STATE parameters on the *IMPORT option. The results at the end of the second analysis should be identical to the results at the end of the first analysis when UPDATE=NO, STATE=YES.
Verification tests using first-order reduced-integration elements with enhanced hourglass control for both ABAQUS/Standard analyses are included to test the import of hourglass forces.
The material model used for all the tests is isotropic linear elasticity, together with Mises plasticity. The material properties used are as follows:
The results from the import analysis with UPDATE=NO, STATE=YES are identical to the results from the end of the first analysis. In all cases when STATE=YES, the stresses, elastic strains, and equivalent plastic strains are continuous during the transfer from the first analysis to the second analysis. The displacements, strains, and energy quantities such as the recoverable strain energy are continuous across the two analyses when UPDATE=NO. At the beginning of the second ABAQUS/Standard analysis the displacements and strains start from zero if UPDATE=YES; the elastic strains, stresses, and equivalent plastic strains are set to zero if STATE=NO.

The verification tests outlined in this section are carried out for each element type listed. The finite element model consists of a single element subjected to increasing loads. During the first analysis the element is subjected to loads over two *DYNAMIC steps.

The verification tests outlined in this section are carried out for each element type listed. The finite element model consists of a single element subjected to increasing loads. During the first analysis the element is subjected to loads over three steps. The first step is a *DYNAMIC procedure, the second is a *STATIC springback step, and the final is a *STATIC loading step. The results from the end of the first step of this analysis are transferred to a second analysis in which the element undergoes springback and the final *STATIC loading step. The tests are performed using UPDATE=NO, STATE=YES and UPDATE=YES, STATE=YES on the *IMPORT option. The results at the end of the import analysis should be identical to the results at the end of the first analysis when UPDATE=NO and STATE=YES.

The verification tests outlined in this section are carried out for each element type listed. The finite element model consists of a single element subjected to thermal loads. The first analysis has prescribed initial conditions for the temperature of the element. The element is subjected to a combination of concentrated loads and temperatures during a *COUPLED TEMPERATURE-DISPLACEMENT step. The results from the end of this analysis are transferred to a second analysis that consists of two *COUPLED TEMPERATURE-DISPLACEMENT steps. In this analysis a new element is defined with the same material properties and initial conditions that the imported element had at the beginning of the first analysis. In the first step of the import analysis all the degrees of freedom of the imported element are held fixed and the new element is subjected to the same loads as in the first analysis. During the second step of the import analysis both elements are subjected to identical loads. The tests are performed using UPDATE=NO, STATE=YES and UPDATE=YES, STATE=YES on the *IMPORT option.
The material model used for all the tests is isotropic linear elasticity, together with Mises plasticity. The thermal properties of the material are also taken to be isotropic.
The results for both elements at the end of the second analysis are identical when UPDATE=NO and STATE=YES. When UPDATE=YES, STATE=YES, the results for the two elements are identical for the stresses, elastic strains, and equivalent plastic strains; the thermal strains and total strains differ due to the updated reference configuration.

The verification tests outlined in this section are carried out for each element type listed. During the first analysis a single element has prescribed initial conditions for temperature and a field variable. The material associated with the element has temperature- and field-variable-dependent properties. The element develops stresses when the temperature and the field variable values are changed over the analysis step. The results from the end of this analysis are transferred to a second analysis. In the second analysis a new element is defined with the same material properties and initial conditions that the imported element had at the beginning of the first analysis. During the import analysis both elements are subjected to the same final values for the temperature and field variable. The tests are performed using UPDATE=NO, STATE=YES and UPDATE=YES, STATE=YES on the *IMPORT option.
The material model used for all the tests is isotropic linear elasticity, together with Mises plasticity. Both properties depend on the prescribed temperature and a field variable.
The results for both elements at the end of the second analysis are identical when UPDATE=NO and STATE=YES. When UPDATE=YES, STATE=YES, the results for the two elements are identical for the stresses, elastic strains, and equivalent plastic strains; the thermal strains and total strains differ due to the updated reference configuration.

The verification tests in this section consist of two analyses for each element type listed. The first analysis consists of two blocks of elements initially separated by a small distance. During the first step of the analysis the two blocks are brought together to establish contact. During the second step the blocks are made to slide relative to each other. The material associated with the element is elastic-plastic; the interface between the two blocks has a coefficient of friction of 0.1. The results from the end of the first step of this analysis are transferred to a second analysis in which the two blocks are made to slide relative to each other in a manner identical to that in the second step of the first analysis. The tests are performed using UPDATE=NO, STATE=YES and UPDATE=YES, STATE=YES on the *IMPORT option.
The material model used for all the tests is isotropic linear elasticity, together with Mises plasticity.
The results at the end of the import analysis with UPDATE=NO and STATE=YES are identical to the results at the end of the original analysis. When UPDATE=YES, STATE=YES, the results for the two analyses are identical for the contact stresses; the values for the relative slip of the surfaces differ due to the updated reference configuration.

The tests outlined in this section verify the accuracy of the transfer of rebar layers and embedded elements from one ABAQUS/Standard analysis to another ABAQUS/Standard analysis. The tests are performed for each of the elements listed above.
The tests involve elements with rebar layers or embedded elements subjected to loading over two *STATIC steps in the first analysis. The results from the end of the first step are then transferred to another ABAQUS/Standard *STATIC import analysis. In addition to the imported elements, new elements with rebar layers or embedded elements are defined in the import analysis. These new elements are identical to the initial element definitions of the imported elements in the original analysis. During the import analysis, the imported and the newly defined elements are subjected to loads such that the final loads are identical to those applied at the end of the second step in the original analysis. The import analysis is performed for the combinations UPDATE=NO, STATE=YES and UPDATE=YES, STATE=YES on the *IMPORT option, except for cylindrical elements for which UPDATE=NO, STATE=YES.
The results for the two sets of elements in the import analysis—that is, the newly defined elements and the imported elements—are identical at the end of the analysis when UPDATE=NO, STATE=YES on the *IMPORT option. In addition, these results are identical to the results at the end of the second step of the original analysis. These tests demonstrate that appropriate quantities in the rebar layer and embedded elements—such as the stresses, rebar orientations, strains, etc.—are transferred accurately from one ABAQUS/Standard analysis to another. The only difference in the results at the end of the import analysis when UPDATE=YES is compared to the results when UPDATE=NO are in the kinematic quantities such as the total strains, rebar rotations, etc. When UPDATE=YES in the import analysis, the reference configuration is updated so that the total strains and the rebar rotations at the beginning of the import analysis are set to zero; when UPDATE=NO, the total strains and the rebar rotations are continuous across the transfer from one analysis code to another.
