Features tested
The submodeling capability is tested on patches of shell elements, with 6 degrees of freedom per node, subject to in-plane loading. In Abaqus/Standard general static, static perturbation, dynamic, and steady-state dynamic procedures are used in various combinations for both the global and submodel analyses. A general, nonlinear static procedure (using NLGEOM) is also included in a separate global and submodel analysis. In Abaqus/Explicit an explicit dynamic procedure (with NLGEOM=NO) is used for both the global and the submodel analyses. The dynamic and explicit dynamic procedures are also tested using NLGEOM=YES in both the global and submodel analyses.
Problem description
Model:
All global models have dimensions 0.24 × 0.12 in the x–y plane and use five section points through the thickness of 0.0125.
Material:
Young's modulus | 1 × 106 |
Poisson's ratio | 0.25 |
Density | 1.0 |
Loading and boundary conditions
ux = A(x+y/2), uy = A(y+x/2) at all exterior nodes, and uz = 0 at all nodes. A = 10−3 in the first step and changes from step to step. In the solid submodel this boundary condition is applied to all faces except the face parallel to the y–z plane at x = 0.12. The latter is driven by the global model.
Results and discussion
The amplitudes of all driven variables in the submodel analysis are correctly identified in the global analysis file output and applied at the driven nodes in the submodel analysis.
