  • When a cylindrical structure with helical reinforcing is bent, the reinforcing tends to slide with respect to the inscribed cylinder. Unbonded flexible pipe is an example of such a structure. As a result of an applied curvature, slippage of the layers of helices occurs, leading to the wear and ultimately to fatigue of the reinforcing. Two principal factors affecting the serviceable life are treated: the amount of slip and the change of the curvature of the individual helical wire, which plays a… CONTINUE READING
