Nonlinear dynamic structural analysis using dynamic relaxation with zero damping

The main idea of the paper is to present a dynamic relaxation algorithm that does not require the damping matrix and velocity terms. The general formulation suggested in this article covers the common DRM as well. In order to verify the ability of the new technique, the obtained static and dynamic solutions are checked with the ones found by the other scheme. When the loads are variable and the behavior of the system is extremely nonlinear, the proposed procedure works efficiently.
