thermomechanical response in thermoelastic medium with double porosity

a dynamic two dimensional problem of thermoelasticity with double porous structure has been considered to investigate the disturbance due to normal force and thermal source. laplace and fourier transform technique is applied to the governing equations to solve the problem. the transformed components of stress and temperature distribution are obtained .the resulting expressions are obtained in the physical domain by using numerical inversion technique. numerically computed results for these quantities are depicted graphically to study the effect of porosity. results of kumar & rani [42] and kumar & ailawalia [43] have also been deduced as special cases from the present investigation.
