Effect of irregularity on the propagation of torsional surface waves in an initially stressed anisotropic poro-elastic layer

The paper studies the propagation of torsional surface waves in an initially stressed anisotropic poro-elastic layer over a semi-infinite heterogeneous half space with linearly varying rigidity and density due to irregularity at the interface.The irregularity is taken in the half space in the form of a rectangle.It is observed that torsional surface waves propagate in this assumed medium.In the absence of the irregularity,the velocity equation of the torsional surface wave is also obtained.For a layer over a homogeneous half space,the velocity of torsional surface waves coincides with that of the Love waves.水利论文U#Z.F` X?l u/d0_"D
