Product: ABAQUS/Standard
The ability to define a *SUBSTRUCTURE LOAD CASE with centrifugal loads and apply it on the usage level is tested.
A substructure is defined from a CPE8R element, and a load vector representing centrifugal loading is defined via *SUBSTRUCTURE LOAD CASE using the CENT/CENTRIF option on the *DLOAD option. Four such substructures are then used to model one-quarter of a rotating annular disk in the x–y plane.
The results are identical to those from an analysis without substructures. The displacement of the inner and outer radius at all points on the quarter annulus is 0.1833 and 0.2388, respectively. Both displacements are within 2% of the analytical results.
Uses CPE8R elements with CENT loading.
