摘要

This paper presents an energy-conserving time-stepping algorithm for dynamics of shell structures. We discuss an application of the six-field non-linear shell model with independent three translations and three rotation parameters as the most suitable in the analysis of non-smooth shell structures. The spatial approximation is based on the finite element method. The energy-conserving time-stepping scheme is based on mid-point approximation of the rate equations expressed in state variables. Numerical applications of the algorithm in non-linear dynamics of smooth and branched shells undergoing unlimited motion are presented.
