Abstract
A modified timeintegration method is developed for nonlinear structural dynamics combining controllable algorithmic dissipation of highermodes and, at the same time, conservation of energy as well as linearand angular momentum. Although these features seem to be actually inconsistent, numerical stability with large time steps for dynamic buckling and snapthrough problems as well as for dynamical systems with smooth solutions is guaranteed. Arbitrary implicit, onestep timeintegration schemes with Newmark approximations are suitable for use as basic algorithms for the proposed method. The desired conservation attributes are obtained if the basic algorithm is augmented by energy and momentum constraints. The potential of the suggested algorithm is demonstrated by selected applications to nonlinear dynamics of shell structures.
