Acoustic Transduction - Materials and Devices, Period 31 July 1996 to 31 December 1997, Annual Report. Volume 5.
Abstract
In Actuator Studies, an important advance in piezoelectric generated noise control now permits wider use of acoustic emission as a reliability diagnostic technique. Joint studies with NRL, Washington have developed a completely new d15 driven torsional actuator and the CAV program element has designed an exciting high strain high force inchworm. Finite element analysis continues to be an important tool for understanding the more complex composite structures and their beam forming capability in water. Thin and Thick Thin Film Studies are gearing up to provide the material base for micro-tonpilz arrays. New exploitation of ultra sensitive strain and permittivity measurements is providing the first reliable data of electrostriction in simple solids, and suggesting new modes for separating the polarizability contributors in dielectrics and electrostrictors.
