18 Questions
What type of motion is exhibited by Love waves?
Horizontal motion
Which wave velocity lies between the S-wave velocity in the soil layer and the half-space?
Love wave velocity
What term is used to describe the dependence of Love wave velocity on wavelength?
Dispersion
Why are Love waves considered dispersive?
Because they can only propagate in a layered medium
How are Love waves generated according to A.E.H. Love (1911)?
By trapping S-waves in a soil layer
What kind of waves are responsible for generating Love waves?
Surface waves
What is the direction of mass particle motion for a P-wave?
In the direction of wave propagation
Why are S-waves sometimes referred to as secondary waves?
Because they move slower than P-waves
Which of the following surface waves are subdivided into Rayleigh and Love waves?
Surface waves
How do S-waves affect the instantaneous volume of materials?
No effect on volume
Which wave type is responsible for causing a momentary shape change in materials?
S-wave
What type of waves do not propagate through fluids?
S-waves
What type of motion describes the particle motion in a homogeneous half-space?
Retrograde ellipse in the vertical plane
In a layered and dissipative medium, the path of particle motion is always:
Elliptical
What type of wave is dependent on Poisson's ratio and its velocity is approximately 0.9194 times that of S-wave in a Poisson's solid?
Rayleigh wave
Which scientist explained the mechanism of generation of Love waves in a horizontal soil layer overlying a half-space?
A.E.H. Love
When is the SH-wave trapped in the soil layer according to A.E.H. Love's explanation?
When the angle of reflection at the base of soil layer is more than the critical angle
What type of interference generates horizontally traveling Love waves according to A.E.H. Love's explanation?
Constructive interference of reflected SH-waves from the top and bottom of the soil layer
