...Wenjun Wu; Longxiang Zhu; Yuemin Wang The wave motion of guided waves in pipe bends is still veiled in some mystery, which hinders the application of guided-wave techniques in the inspection of pipelines with bends. Mode repulsion, which exists in the wavenumber versus frequency dispersion curves...

...Nak-Kyun Cho; Haofeng Chen; Donald Mackenzie; Dario Giugliano Pipe bends are generally employed for routing piping systems by connecting to straight pipes but back-to-back pipe bends are often necessary for confined space applications. In order to achieve safe operation under complex loading...

... 10, 2013; published online December 12, 2013. Assoc. Editor: Pierre Mertiny. 12 03 2013 10 09 2013 Pipe bends are regions of geometric discontinuities in the pipe systems used in power plants and most industry recorded failures have been located around similar regions...

...Dan Vlaicu This paper presents the nonlinear shakedown analysis using finite element method for piping bends taking into account the maximum ovality tolerance. The resulting strain state of the stabilized cycle for the pipe bend including the maximum ovality tolerance is compared with the strain...
