ENERGY-CONSERVING INTEGRATION IN SIX-FIELD SHELL DYNAMICS

Summary We propose an energy-conserving algorithm for dynamics of shell structures. The dynamic analysis is performed using the sixfield non-linear shell model, with three independent translations and three rotation parameters. The spatial approximation is based on FEM. Our temporal integration procedure is based on mid-point approximation of the rate equations expressed in state variables. Numerical simulation of non-linear dynamics of the branched shell undergoing multiple turns and large relative deformations is presented.
