Effect of backing material on the transmitting response level and bandwidth of a wideband underwater transmitting transducer using 1-3 piezocomposite

Author: Nicolaides, K ; Nortman, LP ; Tapson, J Date: Jan 2009 Increasing operating depths of autonomous underwater vehicles have necessitated the development of underwater transducers that can operate at a greater depth. This paper investigates the possibility of incorporating rigid backing material ... Read more
Non-axisymmetric vibrations of a transversely isotropic piezoelectric cylinder with different types of electric boundary conditions

Author: Shatalov, MY ; Every, AG ; Yenwong-Fai, AS Date: Apr 2007 Coupled electro-mechanical non-axisymmetric vibrations are considered in a transversely isotropic piezoelectric cylinder with axial polarization. Solutions of the system of equations are found by exact integration using a seven functional ... Read more
Numerical analysis of guided wave transmission through a long defect in a rail rack

Author: Loveday, PW ; Long, Craig S Date: Nov 2022 Guided wave ultrasound has been used to continuously monitor welded rail track by transmitting guided wave ultrasound between alternate transmit and receive stations along the rail. A section of rail was encountered where transmission was not ... Read more
