Influence of gravity, locality, and rotation on thermoelastic half-space via dual model

Samia M. Said

Abstract

In this paper, Eringen's nonlocal thermoelasticity is constructed to study wave propagation in a rotating twotemperature thermoelastic half-space. The problem is applied in the context of the dual-phase-lag (Dual) model, coupled theory (CD), and Lord-Shulman (L-S) theory. Using suitable non-dimensional fields, the harmonic wave analysis is used to solve the problem. Comparisons are carried with the numerical values predicted in the absence and presence of the gravity field, a nonlocal parameter as well as rotation. The present study is valuable for the analysis of nonlocal thermoelastic problems under the influence of the gravity field, mechanical force, and rotation.
