A layerwise approach to piezo-electric plates accounting for adhesive flexibility and delaminated regions

Visco-piezo-elastic parameter estimation in laminated plate structures

“…During the last few years, several numerical models have been developed for the simulation of active structures with piezoelectric sensors and actuators, both surface or embedded ones [1,2]. The effect of the adhesive materials in the static or dynamic response in this type of structure has been studied experimentally [3] and numerical models taking into account the behaviour and properties of the adhesive materials have been proposed [4][5][6].…”

Study on MEMS Thermal Microactuators with Pedestal‐Type Beam Shape and Au Electroplating

“…While various types of microactuators have been developed, including piezoelectric types , electromagnetic types , electrostatic types , and thermal types , we focused on thermal microactuators, which can facilitate simpler structures and allow larger displacement than other microactuators, and we studied the possibilities of U‐type and I‐type devices . In this paper, we describe thermal microactuators which have a pedestal‐type beam shape modified from the I‐type and a thicker electroplated Au layer, developed in order attain much larger displacements.…”

Parameter estimation in active laminated plate structures

“…1,2 The effect of the adhesive materials in the static or dynamic response in this type of structures has been studied experimentally 3 and numerical models that take into account the behaviour and properties of the adhesive materials have been proposed. [4][5][6] For applications where the use of 2D plate or shell equivalent single layer numerical models is required, it becomes necessary to determine the properties of the different constituent materials that best predict the real behaviour of the structure, including damping characteristics. A non destructive inverse method for estimation of material parameters of laminated active plates with surface bonded piezoelectric sensors and actuators was developed, where a finite element higher-order equivalent single layer numerical model which includes the piezoelectric effect is used.…”
