In Abaqus/Standard general static, dynamic, and linear perturbation procedures are used in various combinations for both the global and submodel analyses. In Abaqus/Explicit both the global model and submodel are quasi-static analyses, except for the test that uses the GLOBAL ELSET parameter, which is a dynamic process. In the quasi-static tests each submodel can be driven from any of the global models. The submodeling capability is also tested for a directly input matrix representing an element stiffness in static procedures (general and linear perturbation) in Abaqus/Standard. The scaling parameter in the submodel boundary condition is tested in an Abaqus/Explicit submodel analysis. Problem descriptionModel:All global models have dimensions 8.0 × 1.5 × 1.0. Material:
Loading and boundary conditionsAll global models involving static procedures in Abaqus/Standard and all the analyses in Abaqus/Explicit are subject to the same loading and boundary conditions as depicted in Two-dimensional continuum stress/displacement submodeling. The time history of the loading, the time at which the corresponding submodeled analysis is performed, and the requested file output from the global model are unique to each individual analysis. Smooth-step amplitudes are used to load the quasi-static models in Abaqus/Explicit. All global models involving dynamic procedures in Abaqus/Standard are subject to the same loading and boundary conditions as depicted in Two-dimensional continuum stress/displacement submodeling. For the transient simulations using the direct-integration implicit dynamic procedure, different excitation frequencies of the load can be tested by changing the parameters defined in the input files. As in the static analyses the time history of the loading, the time at which the corresponding submodeled analysis is performed, and the requested file output from the global model are unique to each individual analysis. Results and discussionThe amplitudes of all driven variables in the submodeled analysis are correctly identified in the global analysis file output and applied at the driven nodes in the submodel analysis.
