ABSTRACT

In traditional structural models of slender member structures, such as pipes, cables, moorings and guys, the interface between slender structures and soil is often represented rather incorrectly as a hard contact boundary. This paper demonstrates how a nonlinear geometric fluid representation can produce more natural and more realistic soil/structure interactions within a traditional structural simulation.
