Cable network analysis by a nonlinear programming technique

Abstract Static cable network analysis is an highly geometrically nonlinear problem which can be solved by direct minimization of total potential energy. Theoretical and practical aspects related to extensible (elastic) cable analysis are presented. A finite element approach supports evaluation of potential energy. The nonlinear problem is solved through an optimization code (MINOS). Great flexibility results from the various constraints (linear or nonlinear, equality or inequality) which can be imposed. Applications are presented including special boundary conditions such as unilateral contact without friction. Extension to dynamic analysis is also provided whereas basic information about the software developed is given.
