Propagation of Elastic Waves in Prestressed Media

الملخص EN

3D solutions of the dynamical equations in the presence of external forces are derived for a homogeneous, prestressed medium.

2D plane waves solutions are obtained from general solutions and show that there exist two types of plane waves, namely, quasi-P waves and quasi-SV waves.

Expressions for slowness surfaces and apparent velocities for these waves are derived analytically as well as numerically and represented graphically.
