Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
For geometrically nonlinear structure, the expressions of tangent stiffness matrix and internal forces of shell element are derived by CR (Co-rotational) theory, and the simplified formulation is performed on static analysis of a hinged cylindrical segment and validated by the results of experiment and references. Then, a predictor-corrector procedure with an approximately energy conservation is developed. With the application on nonlinear symmetric motion of a cylinder under two pinching forces, the improved procedure presents a better stability and accuracy than nonlinear Newmark algorithm.
