Abstract

Finite element modelling was employed in two separate applications involving 1-3 connectivity composite transducers: low volume fraction transducers for hydrophone applications; and the influence of the electrode pattern on monolithic and composite arrays. Specifically, the composite microstructure is investigated with respect to the shape and distribution of the ceramic pillar, in addition to the polymer filler material. Particular attention is devoted to the identification of those pillar geometries and distributions which may suppress unwanted lateral resonances within the composite structure. The same approach is adopted to assess the non-resonant behaviour of such transducers, with particular attention to hydrostatic applications
