- Description
- The transference of the surface seismic wave at the loosely bonded common interface of a visco-piezo composite structure is examined in the current work. With the flexoelectric effect taken into account, the structure is composed of a viscoelastic layer embedded on a piezoelectric substrate. The shear stiffness of the upper layer is thought to be described by a KelvinVoigt model. An analytical separable of variable method is used to derive the complex dispersion relation for both electrically open and short circuit scenarios. A numerical example is presented to demonstrate the significant influence of several influencing parameters on the wave's phase velocities and attenuation coefficients. Additionally, a graphic comparison of three rheological models the Maxwell, Newton and KelvinVoigt models is covered. Results indicate that the attenuation curve pertaining to the Maxwell and Newton model is lowest than on the KelvinVoigt model. Some major outcomes are highlighted here as: the prominent influence of bonding parameter is well-proportional to the phase velocity and inversely proportional to the attenuation coefficient, and flexoelectricity has an intensive impact on both phase velocity and attenuation coefficient curves. This theoretical study leads to understanding the piezo-flexo coupling and its potential application to design the sensors, actuators, energy harvesters and nano-electronics. 2024 Wiley-VCH GmbH.
