The analysis of dispersion portraits of Lamb waves propagating in stratified plates satisfying
the orthogonal Wiechert condition reveals the crossing of fundamental Lamb modes, leading …

Detection of an earth's subsurface velocity profile is very essential for geotechnical site
investigation. Basically, multimode Love wave dispersion curves (DCs) can be used for …

The characteristics of multimode Love wave dispersion curves are dependent on various
geophysical parameters, namely shear wave velocity (SWV), layer thickness and density …

It is revealed that the dispersion portraits of guided waves propagating in functionally graded
isotropic plates with an acoustically softer internal layer may exhibit double crossing of the …
