Abstract

The torsional surface wave propagation in an initially stressed aniso tropic poro-elastic layer over a semi-infinite heterogeneous half space with linearly varying rigidity and density due to irregularity at the interface was studied.The irregularity had been taken in the half-space in the form of arectangle.It is observed that to rsional surface waves propagate in this assumed medium.In the absence of irregularity the velocitye quation of torsional surface wave has also been obtained.Further,it has been seen that for a layer over a homogeneous half space,the velocity of torsional surface waves coincides with that of Love waves.
