Experiments on redirection of organ pipe sound by coupling
The Journal of the Acoustical Society of America, 2004It is well known among organ builders that the sound of an organ pipe may be influenced by the addition of closely tuned pipes in the vicinity of the pipe. Rather than being a result of absorption of sound it is hypothesized that the effect is due to the sound being redirected due to coupling between pipes, similar to the coupling between elements in a

Probabilistic Seismic Response of Coupled Tank-Piping Systems
Volume 8: Seismic Engineering, 2016Dynamic analysis is an integral part of seismic risk assessment of industrial plants. Such analysis often neglects proper coupling between structures of coupled systems, which introduces uncertainty into the system and may lead to erroneous results, e.g., incorrect fragility curves, in comparison with the actual behavior of the analyzed structure ...

Coupling between two cylindrical light pipes: a design
Applied Optics, 1976An expression for the transmission characteristics of a conical coupling is derived. This expression is shown to be useful for choosing an optimum coupling length.

Journal of Pressure Vessel Technology, 2012
In this paper, four-point bending experiments are performed to determine the fatigue life of several threaded pipe couplings. It is shown that fatigue life of these couplings can be improved by designing them with more uniform load distribution in the threads, achieved through reducing the global and local stiffness of the coupling.

Fluid structure coupling in guided modes of thin pipes
2012 IEEE International Ultrasonics Symposium, 2012The motivation and objectives of this work come from the recent increasing interest in using guided waves in defect location and characterization for long pipes used in nuclear and chemical industry. The presence of fluid inside and in some cases outside the inspected pipe raises the problem of guided modes dispersion curves.
