“…In recent years, smart structure development has seen great growth and, in the near future, their use will be widespread and devices will be smart. They may be used in accelerometers, strain gauges, microphones, ultrasonic motors, transducers, micro and nano sensors and actuators (Uchino, 1998; Lee, 2005; Chowdhury et al., 2009; Marinakis et al., 2011; Maleki et al., 2012; Murmu and Adhikari, 2013; Amiri Moghadam et al., 2015).…”

In this article, stresses and free-vibration behaviors of annular circular piezoelectric nanocomposite plate reinforced by functionally graded single-walled boron nitride nanotubes (FG-SWBNNTs) embedded in an elastic foundation based on modified couple stress theory (MCST) are explored. The mechanical properties of FG-SWBNNT-reinforced nanocomposite plate are assumed to be graded in the direction of thickness and estimated through the micro-mechanical approach. The governing equations are obtained using the energy method. The natural frequencies and stresses of FG-SWBNNT-reinforced nanocomposite plate are computed using the differential quadrature method (DQM). An excellent agreement is observed between the obtained results and the results in the literature. Influences of the internal radius to the external radius, the thickness to the internal radius ratio, the material length scale parameter, the functionally graded parameter, temperature changes and elastic coefficients on the natural frequencies and stresses of the hollow circular nanocomposite plate are investigated. The results of this research show that the natural frequencies of the piezoelectric nanocomposite plate increase by increasing the material length scale parameter, the elastic foundation parameters, the ratio of the inner radius to the outer radius, the ratio of the thickness to the inner radius, and decreasing the power index and temperature change. The radial stress of the nanocomposite plate varies proportionally to its mode shape. The results can be employed to design smart structures in micro-electro-mechanical systems (MEMS).

“…In order to overcome the above-mentioned drawback, functionally graded piezoelectric materials (FGPMs) have been proposed for actuators (Maleki et al, 2012). Functionally graded materials are the materials in which the compositions gradually change (along with the thickness), resulting in a corresponding change in the properties of the material (Zhu et al, 2001).…”

“…It is a novel interfacial technique to solve the problems associated with the sharp interface between two dissimilar materials (Zhu et al, 2001). A number of researchers have developed FGPMs with spatially varying properties for a specific application (Hauke et al, 2000; Lim and He, 2001; Liu et al, 2007; Maleki et al, 2012). Lead-based piezoelectric materials are extensively investigated in the form of FGPM (Maleki et al, 2012; Zhang et al, 2008).…”

Lead-based piezoelectric materials are extensively investigated in the form of FGPM (Maleki et al, 2012; Zhang et al, 2008). This is due to the fact that these materials possess a large piezoelectric coefficient and electromechanical coupling.…”

In this article, simulation for PbZr0.516Ti0.484 (lead zirconate titanate)–Pt functionally graded piezoelectric material bimorph actuator is carried out. It consists of seven layers of lead zirconate titanate–Pt with a symmetric composition profile from the center (0% Pt, 10% Pt, 20% Pt, 30% Pt, 20% Pt, 10% Pt, and 0% Pt%). The structural parameters which include length, width, and thicknesses of piezoelectric layers and substrate layer (30% Pt) are optimized based on their first resonance frequency. The bimorph actuator based on optimized parameters shows the first resonance frequency at 960 Hz as compared to resonance frequency (7761 Hz) of original design of functionally graded piezoelectric materials. Large actuation is observed in functionally graded piezoelectric materials of proposed design. The proposed functionally graded piezoelectric material actuator can be effectively used at low frequency (960 Hz) with high tip displacement (35 µm) under 500 V. This work is helpful in fabricating functionally graded piezoelectric materials for specific applications.
