چکیده

The aim of this paper is to investigate the influences of rotation, magnetic field, initial stress, and gravity field on Rayleigh waves in a homogeneous orthotropic elastic medium. The government equations is solved by Lame’s potential and obtained the frequency equation which determines the velocity of Rayleigh waves, including rotation, initial stress, gravity field, and magnetic field, in a homogeneous orthotropic elastic medium has been investigated. Numerical results analyzing the frequency equation are discussed and presented graphically. The results indicate that the effect of rotation, initial stress, magnetic field, and gravity field on Rayleigh wave velocity are very pronounced. Comparison are made with the results in the absence of rotation, initial stress, magnetic field and gravity field. Mathematics Subject Classification: 41.20.Jb
