Impact of Prestressed Anisotropic Porous and Prestressed Anisotropic Magnetoelastic Layers on a Love-Type Wave
Publication: International Journal of Geomechanics
Volume 23, Issue 9
Abstract
The present study is carried out to investigate the traversing of a Love-type wave in a prestressed anisotropic magnetoelastic stratum (PAMES) bounded between a prestressed anisotropic porous upper substrate (PAPUS) and prestressed anisotropic porous lower substrate (PAPLS). The exact solution of the governing equations is acquired and explained in detail for various effective parameters. Irregular boundary conditions have been employed for both the interfaces of the sandwiched layer. The variable separable technique has been used to determine the exact solution of the governing equations. The impacts of diverse parameters such as prestress, anisotropic porosity, anisotropic magnetoelasticity, irregularity parameters on phase, and damped velocity of Love-type wave have been discussed. This model contains huge potential to deal with many commercial and industrial applications in acoustical engineering, geotechnical engineering, ultrasonics, earthquake engineering, and geophysics. Results indicate that the anisotropic magnetoelastic parameter possesses a positive impact on phase and damped velocity. The damped velocity converges to some constant magnitude for distinct values of the porosity parameter.
Practical Applications
This is a theoretical work on the seismic wave propagation of surface waves. In this work, the seismic tremor, the soil components, and the transducers are made with the help of both theoretical and numerical calculations. This research could have also been used in acoustic design, earthquake engineering, geophysics, and ultrasonics. Seismic waves are also applicable for forecasting. This can be improved by putting a porous material on the structure's free surface. The goal of looking at different physical situations is to find ways that the results of this study can be used in science, technology, or the field of geotechnics. Geotechnical engineering is an integral part of civil engineering that looks at how earth materials work in engineering. Geotechnical engineers use soil properties, such as porosity, void ratio, permeability, and so forth, to analyze site conditions and plan earthworks, retaining structures, and foundations. The surface wave survey method is under continuous evolution. On a small scale, it can be used to describe a medium without touching it. On a large scale, it can be used to do a geotechnical survey after an earthquake. Even though the sizes of these applications are very different, they all use the way surface waves move along the edge of a layered medium.
