THE FEM MODEL OF GEOMETRIC NONLINEAR BEHAVIOR CABLE IN THE ASPECT OF DYNAMICS

Abstract

The paper concerns to the modeling of dynamic of cable element which exhibits nonlinear geometric nonlinear behavior in terms of fourth order effect and in aspect of non-compressible characteristic utilizes Finite Element Method. The derivation bases on variational principles in which strain be evaluated by Green's tensor. At point of time, displacement, deformation, stress at equilibrium configuration have been obtained by iteration method’s Newton- Raphson via tangent stiffness matrices. Moreover, a vanishing of stiffness of slack cable and their effectiveness on distribution of structure stiffness, so lead to iterations be more complex and procedure.
