The transient analysis of viscoelastic functionally graded porous (FGP) nanoplate resting on the viscoelastic medium using the finite element method (FEM) is studied in this work. The nanoplate is made from a material that varies in thickness and has mechanical qualities that change depending on the porosity. The whole of the mechanical system rests on a Pasternak medium, which is modeled in accordance with a Kelvin–Voigt viscoelastic model. The general plate motion balance equations are developed by the application of the higher‐order shear plate theory (HSDT) with a new inverse hyperbolic function, the nonlocal hypothesis, and Hamilton's principle. In order to develop a four‐node quadrilateral element, Lagrangian and Hermitian interpolation functions are used. These functions are employed to define the main variables that correspond to the in‐plane displacements and the transverse displacements, respectively. The direct integration method developed by Newmark is used to calculate the dynamic responses of the plate. The outcomes that were anticipated by the essay have been confirmed by reputable sources. The dynamic response characteristics of a viscoelastic FGP nanoplates that is placed on a viscoelastic medium are explored, and a number of factors that influence these features are discovered and explained.

Photoluminescent (PL) layers and electroluminescent (EL) systems have gained significant attention for their applications in constructing flat panels, screen monitors, and lighting systems. In this study, we present a groundbreaking approach to fabricating temperature sensors using barium-calcium zirconium titanate (BCZT) with thermo-optic properties, leading to the development of opto-thermal sensors for electric vehicle battery packs. We prepared zinc sulfide (ZnS) fluorescent films on BCZT ceramics, specifically two optimal compositions, BCZT0.85 (Ba0.85Ca0.15Zr0.1Ti0.9O3) and BCZT0.9 (Ba0.9Ca0.1Zr0.1Ti0.9O3), via the solid-state reaction method for the dielectric layer. The BCZT powders were calcined at varying temperatures (1200 and 1250 °C) and dwell times (2 and 4 h). The resulting phase formation and microstructure characteristics were analyzed using X-ray diffraction and scanning electron microscopy, respectively. Our investigation aimed to establish a correlation between the dielectric behavior and optical properties to determine the optimal composition and conditions for utilizing BCZT as thermal detectors in electric vehicle battery packs. All BCZT powders exhibited a tetragonal phase, as confirmed by JCPDS No. 01-079-2265. We observed an increase in the dielectric constant with higher calcining temperatures or longer dwell times. Remarkably, BCZT0.85 ceramic sintered at 1250 °C for 4 h displayed the highest dielectric constant of 15,342, establishing this condition as optimal for preparing the dielectric film with a maximum dielectric constant of 42. Furthermore, we investigated the temperature-dependent electroluminescence intensity of the samples, revealing a significant enhancement with increasing temperature, reaching its peak at 80 °C. Additionally, we observed a positive correlation between electroluminescence intensity and dielectric constant, indicating the potential for improved opto-thermal sensors. The findings from this study offer promising opportunities for the development of advanced opto-thermal sensors with potential applications in electric vehicle battery packs. Our work contributes to the expanding field of photoluminescent and electroluminescent systems by providing novel insights into the design and optimization of efficient and reliable sensors for thermal monitoring in electric vehicle technologies.
