Abstract:
The model of generalized thermoelasticity, dual-phase-lag model (DPL), is applied to study the influence of gravity on a piezo-thermoelastic diffusive medium. Normal mode analysis is used to obtain the expressions for different physical quantities. The derived expressions are computed numerically and the results are presented in graphical form. Comparisons are made with the results predicted by Lord–Shulman theory (L–S) and DPL model in the presence and absence of gravity.
