Abstract
In the present paper, we have introduced the three phase lag theory to study the dynamical interactions in a thermoelastic medium. Normal mode analysis technique is employed onto the non-dimensional field equations to obtain the analytical solution. The numerical estimates of the field variables displacement, stress and temperature are computed for magnesium crystal like material and presented graphically. Comparisons of the physical quantities are shown in figures to study the effect of three phase lag parameters and time. Numerical results predict finite speed of propagation for thermoelastic waves.
