Product: ABAQUS/Standard
The model consists of two substructures, each generated from truss elements of type T3D2. The model is oriented along the 
-axis and is constrained at one end in all degrees of freedom. It is free to move only in the -direction at its other end. In each case the truss is displaced by 25.4 mm (1 in) at its free end in an initial *STATIC step. It is then released in the *DYNAMIC (or *MODAL DYNAMIC) step, and the displacement response history is saved on a file for postprocessing.
The results from the substructure analysis exactly match the results that are obtained when substructures are not used.
