Kinematics in tensioned structures

Abstract

Movement in tensioned structures can be found on three different layers. On the microscopic layer the sliding of molecular chains in polymer fibers or the sliding in the crystalline grid in steel wires is used get material with high strength. On the second layer tensioned structural elements such as cables, belts and fabric made of high strength wires and yarns are showing several movements under tension influencing the stress and strain behavior, the long term behavior and the possibility of folding and bending with less strain. On the third layer the behavior of tensioned structures is described by movement and strain less deformations depending on the curvature, pretension and installation process.
