Transferring results of an analysis model multiple times

The verification problems presented in this section test the transfer of results of selected sets of elements multiple times from an Abaqus/Standard analysis to an Abaqus/Explicit analysis.

The model in each test consists of disjoint blocks of various types of elements subject to concentrated loads applied at one end of each block. The blocks are laid out in the X–Y plane, and all elements have elastic material properties. In Step 1 the static response is computed in an Abaqus/Standard analysis. In Step 2 the model and results at the end of Step 1 are imported into an Abaqus/Explicit analysis; the loading and boundary conditions from the previous analysis are maintained. In some tests the model is imported once and relocated by a 90° rotation of the model about the z-axis. In other tests the model is imported twice, first at the same location of the previous analysis and then at a new location that results from a 90° rotation of the model about the z-axis. The response of Step 2 in the import analysis is compared to that of Step 1 in the previous analysis.

The model in each test consists of disjoint blocks of various types of elements subject to concentrated loads applied at one end of each block. The blocks are laid out in the X–Y plane, and all elements have elastic material properties. In Step 1 the steady-state response is computed in an Abaqus/Explicit analysis. In Step 2 the model and results at the end of Step 1 are imported into another Abaqus/Explicit analysis; the loading and boundary conditions from the previous analysis are maintained. In some tests the model is imported once and relocated by a 90° rotation of the model about the z-axis. In other tests the model is imported twice, first at the same location of the previous analysis, and then at a new location that results from a 90° rotation of the model about the z-axis. The response of Step 2 in the import analysis is compared to that of Step 1 in the previous analysis.

The quarter circular plate model is assembled from a part consisting of elastic-plastic S4R shell elements. Uniform pressure loading is applied on the top surface of the plate. The circular edge is clamped, and symmetry boundary conditions are specified along the cut edges. In Step 1 an Abaqus/Standard analysis is performed to compute the static response. In Step 2 the quarter model and results at the end of Step 1 are imported into an Abaqus/Explicit analysis four times: first at the original location, then relocated with rotations of 90°, 180°, and −90°. The result is a model for the whole circular plate with the four quarter circles disconnected along the original cut edges. Tie constraints are defined to connect these edges so that the response of the model corresponds to that of a continuous plate. The Abaqus/Explicit import analysis is performed with the same loading as in the previous static Abaqus/Standard analysis, and the clamped boundary conditions on the circular boundary are maintained.

The quarter model of the forming of a conical aluminum shell consists of elastic S3 and S4R shell elements pressed against an outer mold modeled as a rigid body of C3D8R elements. Uniform pressure loading is applied on the shell surface. A contact pair is defined for the surfaces of the shell and the mold, and surface smoothing of a variety of geometries is specified between the contacting surfaces. The reference node of the rigid mold is fixed, and symmetry boundary conditions are specified along the cut edges. In Step 1 an Abaqus/Standard analysis is performed to compute the static response. In Step 2 the quarter model and results at the end of Step 1 are imported into an Abaqus/Standard analysis four times: first at the original location, then relocated with rotations of −90°, −180°, and −270°. The result is a model for the whole conical shell with the four quarter shells that are disconnected along the original cut edges. For verification purpose these edges are not tied. The Abaqus/Standard import static analysis is performed with the same loading as in the previous static Abaqus/Standard analysis, and the fixed boundary conditions on the reference nodes are maintained.
