摘要

本研究探讨了湿热条件下半无限压电材料中压电波与热湿扩散之间的复杂相互作用。通过采用二维笛卡尔框架,为受湿效应影响的热压电正交介质建立了新的控制方程。利用法模分析获得了关键参数的精确表示。研究探讨了水分含量、扩散率和温度扩散率等关键因素对各种物理场空间分布的影响。此外,还强调了一种具有重要意义的特殊情况。这些结果有望改善传感器、致动器和能量收集装置的性能和可靠性。

Response of Moisture and Temperature Diffusivity on an Orthotropic Hygro-thermo-piezo-elastic Medium

This research explores the complex interaction between piezoelectric waves and heat-moisture diffusion within a semi-infinite piezoelectric material under hygro-thermal conditions. By employing a two-dimensional Cartesian framework, novel governing equations for a thermo-piezoelectrically orthotropic medium influenced by moisture effects are developed. Accurate representations for key parameters are obtained by utilizing normal mode analysis. The investigation examines the influence of critical factors like moisture content, diffusivity, and temperature diffusivity on the spatial distribution of various physical fields. Additionally, a particular scenario of significance is highlighted. These results have the potential to improve sensor, actuator, and energy-harvesting device performance and dependability.
