In this paper a mesh-free model of the functionally graded material (FGM) plate is presented.  The piezoelectric material as a sensor and actuator has been distributed on the top and bottom of the plate, respectively. The formulation of the problem is based on the classical laminated plate theory (CLPT) and the principle of virtual displacements. Moreover, the Particle Swarm optimization (PSO) ...

Owing to inhomogeneous strain and high surface-to-volume ratio in nanostructures, it is imperative account for the flexoelectricity as well surface effect while analyzing size-dependent electromechanical responses of nano-scale piezoelectric materials. In this article, a semi-analytical ‘single-term extended Kantorovich method (EKM)’ ‘Ritz method’ based powerful framework developed investigatin...

Abstract A one-dimensional piezoelectric phononic crystal (PPC) consisting of a periodic pattern made two perfectly bonded materials: one active (piezoelectric), the other passive (elastic) and exhibiting strong acoustic impedance contrast is studied. We are interested in tunability inclusions order to control propagation ultrasonic waves MHz range from nonlinear electrical component connected ...
