Abstract:
As micropolar theory explains the material's inner structure and behavior; therefore, it is more appropriate for various geological materials including soils and rocks. Micropolar materials are characterized as a substance with properties such as molecules of the dumbbell form and atoms of dipole nature, which are present on body couples and surface. The target of this study is to see the influence of the magnetic field, angular velocity, initial stress, and rotation on the incident SV wave. The SV waves are reflected as well transmitted at the interface of micropolar solid and liquid half-space. The dual-phase lag theory is used for energy equation; the basic equations have been discussed to drive results for transmitted thermal and P waves and reflected thermal, micro-rotation, SV and P waves. The transmission and reflection of SV waves are examined after applying the boundary conditions, and amplitude ratios are figured by the matrix inversion method. Graphs are sketched and discussed for various values pertinent parameters on amplitude ratios. We observe the outcome of a magnetic field, angular velocity, and initial stress on the refraction and reflection of SV wave in the context of DPL theory at micropolar solid and liquid layers. The amplitude ratios of reflected SV wave start from its minimum value and moves towards unity. The amplitude ratio of the reflected P wave is more prevalent. The transmitted P and T wave show a small change in amplitude ratio.
