Abstract

The object of the present paper is to investigate the joint effect of couple-stress and gravity on the propagation of waves in an elastic layer. It is found that the velocity of propagation of waves in an elastic layer increases due to the presence of couple-stress and the effect of gravity has some effect on the wave velocity when the length of the wave is small compared with the thickness of the layer. It is clear from the phase velocity equation that joint effect of couple-stresses and gravity is superposing effect when this two are acting separately.
