A domain of influence theorem for thermoelasticity with dual phase-lags

Abstract

The aim of the present work is to establish the domain of influence theorem for a potential-temperature disturbance under the generalized thermoelasticity with dual phase-lags. We prove that for a finite time t0, the potential related to the displacement and the temperature fields generate no disturbance outside a bounded domain. The domain of influence is shown to be dependent on the thermoelastic coupling constant and two phase-lag parameters. Copyright © Taylor & Francis Group, LLC.
