Abstract

This article deals with the theoretical investigation of deformations in a rotating isotropic functionally graded double porous thermoelastic material (FGDPTM) with voids by means of two temperature Green-Naghdi III (G-N III) model of generalized thermoelasticity. A gravitating magneto-double-poro-thermoelastic two-dimensional substrate is influenced by both thermal shock and inclined mechanical load at the free surface. The normal mode technique is carried out to derive the expressions for displacements, temperatures, volume fractions, and stresses. Numerical values for copper-like material are utilized to execute several graphical implementations representing the variations in the aforementioned variables in the presence and absence of different parameters. Furthermore, comparative studies among FGDPTM, functionally graded porous thermoelastic material (FGPTM), and functionally graded thermoelastic material (FGTM) structures are displayed graphically with and without two temperatures.

摘要

本文通过广义热弹性的两个温度Green-Naghdi III（GN III）模型，对具有空隙的旋转各向同性功能梯度双多孔热弹性材料（FGDPTM）的变形进行了理论研究。磁性双孔​​热弹性二维基板受自由表面热冲击和倾斜机械载荷的影响。执行普通模式技术可以得出位移，温度，体积分数和应力的表达式。利用铜样材料的数值来执行几种图形实现，这些图形实现表示在存在和不存在不同参数的情况下上述变量的变化。此外，FGDPTM之间的比较研究
