Study of micro‐elongated thermoelastic medium loaded with a piezoelectric layer under the influence of gravity using the dual‐phase‐lag model

Abstract This paper aims to examine the influence of gravity on a thermoelastic micro‐elongated layer when piezoelectric is above it, utilizing theory Lord–Shulman (L–S) and also model dual‐phase‐lag (DPL). A partial differential equation was transformed into an ordinary using normal mode analysis. Aluminum epoxy numerical computations are carried out, results presented in graphical format. The L–S DPL compared presence absence it found that has quite massive all physical quantities.
