ABSTRACT
This research article is concerned with the analytical assessment and mathematical modelling
to unveil the characteristic of a torsional wave in the irregular Earth’s crustal stratum. This
investigation has been performed to clarify of possible occurrence of the torsional wave
in an irregular self-reinforced composite layer bonded between dry sandy media and an
isotropic elastic half-space. Rectangular and parabolic irregularities have been assumed at
the interface of the intermediate layer and the lower half-space. In order to acquire the
required dispersion equation, the appropriate boundary conditions with the assistance of
displacement and stress components have been well satisfied. The effects of different affecting
parameters such as reinforcement, sandiness, initial stress and irregularity parameters have
been explored and explained by suitable graphs. Moreover, a comparative study has also
been accomplished graphically for rectangular, parabolic, and no irregularities.
