• Resumen

  • 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-doubleporo-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 copperlike 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.
