000022165 520__ $$2eng$$aIn this paper, we present the DE3 integration scheme. This unconditionally stable scheme is dedicated to the numerical integration of linear structural dynamics problems and offers a simple and easy to use high-order alternative to the second-order accurate ones that are usually employed. Its symmetric formulation makes it an interesting candidate to simulate large-scale problems. In addition, the scheme offers the possibility to control the introduced numerical damping via a single algorithmic parameter, which is very convenient for the filtering of the spurious oscillations that can arise from large stiffness contrasts in certain models. The properties of high-order accuracy and numerical damping are illustrated by way of a demonstrative example.
