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.
