FORCED WAVE PROPAGATION IN VISCOELASTIC CABLE WITH SMALL SAG

摘要

Based on the linear viscoelastic differential constitutive law and cable structural model, the coupled longitudinal-transverse waves that propagate along a viscoelastic cable with small curvature is investi- gated. A mathematical model is presented that describes the three-dimensional nonlinear response of a vis- coelastic cable. An asymptotic form of this model is obtained for the linear response of cables having small equilibrium curvature.
