“…For this crystallographic cut, the velocity of the longitudinal plane waves is 6781 m/s and the coupling coefficientK t is equal to 0.564 as it can be seen respectively in Figs. 11a and 7 of [36]. It can be noticed that an error has appeared in [36] since the numerical value ofK t was given to be equal to 0.6 instead of 0.564.…”

“…11a and 7 of [36]. It can be noticed that an error has appeared in [36] since the numerical value ofK t was given to be equal to 0.6 instead of 0.564. This comes from the fact that the computation was led for a numerical pre-stress of +3 GPa instead of +2 GPa.…”

“…The KLM model was extensively studied in the case of pre-stress free piezoelectric films and multilayers [32][33][34][35][36][37]. As the KLM formalism corresponding to the case of a pre-stressed piezoelectric plate was previously developed for the natural coordinate system [36], only the expressions of the final parameters directly implied in the KLM model are expressed. In order to illustrate its formalism, the case of a unique longitudinal plane wave that propagates along the x 3 axis is considered.…”

In this study, a characterisation method for graded porosity piezoceramic discs is presented. A sample with graded porosity from about 5 to about 40% along the thickness has been produced. Two homogeneous samples with respectively low and high porosity are used as references. Density measurements have been performed in order to estimate the average porosity of samples. Using an equivalent circuit model including the mechanical and dielectric losses and a fitting technique, the electroacoustic properties of the constant porosity samples have been extracted. Then, based on a model of multilayer piezoceramics, the graded porosity sample properties are simulated assuming it is made of 10 layers stacked along the sample thickness.

“…Usually these multi-layered devices can elaborate original transducers such as Dual-frequency or Barker Code transducers or 2-D array elements with relative low electrical impedance, which lead to a greater sensitivity compared with single-layer element (Desmare, 1999). If they are made of piezoelectric polymeric materials, these devices can also offer some advantages over piezoelectric ceramic transducers, including flexibility, ease of preparing large sheets and the ability to undergo large deflections without damage (Marcus, 1984).…”

Taking the bonding layers and electrodes into account, the multi-layered piezoelectric cantilevers are studied based on the theory of elasticity. Different from the traditional investigations based on the elementary theory of elasticity, the Airy stress function method is used in the present paper. The stress function and induction function are proposed and determined, and then the exact solutions of the static governing equations are found. The material properties and thickness of different layers may be different in the present investigations. As two special cases, the exact static solutions for both unimorph and bimorph are directly obtained by using the present general solutions. The exact solutions obtained in the present paper are compared with the numerical results and others' investigations, and good agreements are found. In addition, the effects of the properties of both bonding layers and electrodes are discussed. Moreover, the present solution can be used for function graded piezoelectric cantilever beams when the thickness of each bonding layer is taken as zero.
