Abstract
An FEM eigenvalue analysis program for such sheet winding products as CFRP golf club shafts is developed. A new cylindrical beam element is formulated considering the coupling effect between tension and torsion for anisotropic materials. In order to verify the coupling effect of the presented method, composite cylindrical cantilevers are analyzed. And the non dimensional torsion by the axial tension of the beam element model is compared with a shell element model. And the influence of coupling effect on the natural frequencies of CFRP golf club shafts is evaluated for various fiber angles by eigenvalue analyses.
