“…Todays, functionally graded material (FGM) together with functionally graded intelligent materials such as functionally graded piezoelectric material (FGPM) and functionally graded magneto-electro-elastic (FGMEE) have ever-increasing usages in the various industries because of their excellent feature. [1][2][3][4][5] Also, magneto-electro-elastics as composites including both piezoelectric and magnetostrictive components exhibit better performance than single-phase smart material as a result of the magneto-electric interaction effect. 6 Consequently, as a new type of intelligent materials, FGMEEs are considered and employed as high performance sensors and actuators in smart structures.…”

Effects of porosity, profile of thickness and angular deceleration on the stress and deformation of a fluid-saturated functionally graded porous magneto-electro-elastic rotating disc are investigated in this article. Since the angular velocity is taken to be variable, the disc is subjected to Lorentz force in two directions: radial and circumferential. It is assumed that material properties of the disc obey power-law function of radius. The disc is uniformly porous and its thickness varies as a function of radius. First, three coupled governing partial differential equations in terms of the displacement and electric potential are converted to ordinary differential equations employing the separation of variable method. Then, obtained equations are solved using the Runge–Kutta and shooting methods for the case of fixed–free boundary condition. The effect of variable angular velocity, thickness profile, inhomogeneity index, porosity, and magnetic field is studied and illustrated graphically. The results demonstrate that considering angular acceleration for the disc has a considerable effect on the Lorentz force resulted from the magnetic field. Besides, the angular velocity constant has a significant effect on the stresses and displacements in the presence of the magnetic field.

“…So the present host circular cylindrical shell is considered to be made of FGM and the effect of its temperature on the actuation capability of SPFRC is also another objective of this study. It may be noted here that the literature shows a substantial number of studies on the analysis of FG/laminated composite circular cylindrical shell integrated with monolithic piezoelectric/PZC actuators (Carrera et al, 2011; Chen and Shen, 1996; Dogan and Vaicaitis, 1999; Ganesan and Kadoli, 2003; He et al, 2002; Jafari et al, 2014; Kumar et al, 2008; Lester and Sylvie, 1993; Li et al, 2004; Liew et al, 2002; Qiu and Tani, 1995; Ray and Reddy, 2005; Saadatfar, 2015; Sheng and Wang, 2009; Sonti and James, 1996; Zhang et al, 2008). But none of the available studies addresses the actuation capability of SPFRC actuator especially in comparison to the same of monolithic piezoelectric/PZC actuator.…”

For improved flexibility and conformability of piezoelectric fiber–reinforced composite actuator, it is reconstructed in a recent study by the use of short piezoelectric fibers (short piezoelectric fiber–reinforced composite) instead of continuous fibers (continuous piezoelectric fiber–reinforced composite). This modification facilitates its application in short piezoelectric fiber–reinforced composite layer form instead of continuous piezoelectric fiber–reinforced composite patch form particularly in case of host structures with highly curved boundary surfaces. But the corresponding change in actuation capability is a major issue for potential application of short piezoelectric fiber–reinforced composite that is studied in this work through the control of vibration of a functionally graded circular cylindrical shell under thermal environment. First, an arrangement of continuous piezoelectric fiber–reinforced composite actuator patches over the host shell surface is presented with an objective of controlling all modes of vibration. Next, the use of short piezoelectric fiber–reinforced composite actuator layer for similar control activity is demonstrated through an arrangement of electrode patches over its surfaces. Subsequently, an electric potential function is assumed for the consideration of electrode patches and a geometrically nonlinear coupled thermo-electro-mechanical incremental finite element model of the harmonically excited overall functionally graded shell is developed. The numerical results reveal actuation capability of short piezoelectric fiber–reinforced composite actuator layer with reference to that of the existing continuous piezoelectric fiber–reinforced composite/monolithic piezoelectric actuator patches. The effects of temperature, size of electrode patches, properties of piezoelectric fiber–reinforced composite, and functionally graded properties on the control activity of short piezoelectric fiber–reinforced composite/continuous piezoelectric fiber–reinforced composite actuator are also presented.
