Linear and Nonlinear Elastodynamics of Nonshallow Cables
A geometrically exact mechanical model describing large motions of nonshallow elastic cables is employed to investigate the linear and nonlinear properties of the cable planar modes. Considering the potential and kinetic linear modal energy content, it is shown that the elasto-static and elastodynamic modes are located around the various crossover lines and they become closer for deeply sagged cables. The nonlinear characteristics of the modes of different type are documented and general properties are unfolded.
