Extensible Cable Network Analysis through a Nonlinear Optimization Code
Cable networks are geometrically highly nonlinear structures. This paper presents an elegant way to find the equilibrium shape of extensible cable networks by minimization of total potential energy. Both theoritical and practical aspects of the method are described below. Some applications are presented, including cases with special boundary conditions such as unilateral contact without friction. Finally, it is shown how a dynamic analysis can be performed and some information about the developed software is given.
