“…If the process is reversed, an outer electrical field can both as stretch as compress the piezoelectric material. In present days, such properties of piezoelectric materials are used in many applications [3] involving the production and detection of sound, fabrication of sensors [4], production of filters and other high-frequency applications [5], generation of high voltages and electronic frequency, piezoelectric actuators [6], high voltage actuators in robotic area [7], ultrasonic motors [8] and many other applications.…”

We describe the phenomenon of generation of an external field of forces from piezoelectric materials subjected to the application of electric fields or mechanical stress. We show that piezoelectric materials are capable of producing nonlocal forces of induction in external objects and we conclude that the nature of the forces generated is not originated from traditional interactions. Further we specifically assert that the generation of forces by the piezoelectric materials is ruled by the hypothesis of preexisting condition of generalized quantum entanglement between the molecular structure of the material bulk and the surrounding environment. In addition, the widely spread coupling of the molecules with the environment can be manifested from the so-called direct effect or the converse effect in piezoelectric materials and this coupling is not intermediated by acoustic waves or electromagnetic fields. We show that the novel effect has a theoretical explanation consistent with the generalized quantum entanglement framework and the direction of the induced forces depends on either the direction of the mechanical force or the electric field applied in these materials.

“…[1][2][3][4] In piezoelectric composite materials, the high piezoelectric and dielectric properties of lead zirconium titanate (PZT) ceramics combined with the low density and the high flexibility of polymers 5 make them suitable for aforementioned applications. Among these composites, 0-3 and 1-3 type composites have received much attention.…”

Structured lead zirconium titanate (PZT)-epoxy composites are prepared by dielectrophoresis. The piezoelectric and dielectric properties of the composites as a function of PZT volume fraction are investigated and compared with the corresponding unstructured composites. The effect of poling voltage on piezoelectric properties of the composites is studied for various volume fractions of PZT composites. The experimentally observed piezoelectric and dielectric properties have been compared with theoretical models. Dielectrophoretically structured composites exhibit higher piezoelectric voltage coefficients compared to 0-3 composites. Structured composites with 0.1 volume fraction of PZT have the highest piezoelectric voltage coefficient. The flexural strength and bending modulus of the structured and random composites were analyzed using three-point bending tests.

“…Piezoelectric material comprises one of the main categories of smart materials which are implemented in the construction of smart structures. Smart structures have the capability to sense changes and adapt to them [1]. Piezoelectricity is an electro-mechanical phenomenon which is exhibited in materials with certain chemical structures.…”

In this paper, a new 12-node triangular element is developed for the analysis of composite plates. Moreover, the stress-strain relations of laminated bending plates, along with the characteristics of composite and piezoelectric materials have also been investigated. Following this, a finite element formulation for smart composite bending plates is proposed. The capability of the suggested element in analyzing both composite plates and smart ones is studied via numerical examples. These analyses demonstrate that the proposed element is capable of yielding accurate results for the given problems. In addition, it is also concluded that in comparison to the elements developed by other researchers, this new formulation leads to more precise outcomes.
