3.6.4 Cylindrical continuum stress/displacement submodeling

Product: ABAQUS/Standard

Elements tested

CCL9 CCL12 CCL18 CCL24

Features tested

The submodeling capability is applied to cylindrical elements. The general static procedure is used in various combinations for both the global and submodel analyses.

Problem description

Model:

All global models consist of an 180° cylindrical segment with an outer radius of 2 and an inner radius of 1. The submodel input files model the right half of the global model. The submodel driven nodes lie along the symmetrical plane of the global model.

Material:

Young's modulus	6 × 10⁶
Poisson's ratio	0

Loading and boundary conditions:

All the nodes at both ends are fixed in the circumferential direction, and all the nodes at the inner surface are constrained in all degrees of freedom. Distributed loads or prescribed displacements are applied at the outer surface of the cylindrical elements.

Results and discussion

The amplitudes of all driven variables in the submodeled analysis are correctly identified on the global analysis file output and applied at the driven nodes in the submodel analysis.
