Development of an anisotropic co-rotational beam model including variable cross-section

The aim of this article is to expand the general approach of the flexible beam model to consider tapered geometry and anisotropic properties by updating the cross-sectional stiffness matrix. The advantage of this approach is that continuously variable cross-section, as well as irregular axes on the...
