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

The aim of this article is to expand the general approach flexible beam model consider tapered geometry and anisotropic properties by updating cross-sectional stiffness matrix. advantage that continuously variable cross-section, as well irregular axes on cross-sections, are considered simultaneously co-rotational method. Anisotropic isotropic cantilevered cases simulated. A static force or moment applied external load. NREL 5 MW wind turbine blade analyzed a practical example. results compared against existing literature ABAQUS model, they show excellent agreement.
