Abstract: “In this paper, we present a curvature based modification to the existing beam element formulation to model cables which undergoes large displacements. The proposed approximation is numerically tested against the P-delta formulation and true nonlinear formulation of cables. As a result, a limiting value for the curvature based stiffness is reported.”

Keywords: cables, finite elements, small strains, geometric nonlinartity, large displacements.
