摘要: Abstract A finite difference formulation for the equations of SH waves in viscoelastic media has been developed and applied to problem an infinite half space with a buried source emitting compressional pulse. dispersion relation by employing (FD) method, which used discuss stability criteria also obtaining phase group velocities media. Furthermore, effect variation parameter on velocities; wave propagation increase parameter; change at different locations from have studied. The are found be dispersive velocity increases decrease parameter. location important strength that intensity therefore its longevity is inversely proportional distance source, implying will progressively die out exponentially.
