Product: ABAQUS/Standard
The ability to incorporate degenerated elements into a substructure definition is tested.
A planar substructure is formed from standard CPS8 elements and CPS8 elements degenerated into 6-node triangles. Both displacement degrees of freedom are retained at selected nodes on the substructure that is constrained as depicted below, and a displacement of 0.2 in the x-direction is prescribed for the three nodes along x=1.0.
The results are identical to the analytical results where a stress of 6 × 106 develops in the direction of extension.
Uses CPS8 and degenerated CPS8 elements.
