Abstract Focusing on the requirements of rapid damage location test for multi-layer steel plates penetration cylindrical structure in complex and harsh environment, this paper studies propagation characteristics high-speed impact stress waves plates. Also, measurement effects near zone hole are compared with different sensors, so as to select appropriate PZT sensors measure velocity wave actual...

Aiming to gain an accurate prediction model of the vibro-acoustic problem for vibrating structure systems, uncertainty vibration analysis cylindrical shell considering construction factors is investigated. The generalized polynomial chaos (GPC) method used analytical solution free structure, in which factors, comprising material parameter and geometric parameter, are considered. By combining co...

In the present study, effects of different oblique angles and diameters on cylindrical weir below a gate as combined device have been studied experimentally. For this purpose, sixteen models weir-gate structures tested in laboratory flume. These had four α (300, 450, 600, 900). each angle, diameter changed times (4, 7.3, 9, 11cm). The results all indicate that theoretical discharge (Qth) is inv...
