The effect of topography and subsurface inhomogeneity on surface stress amplification during Rayleigh wave interaction is experimentally investigated. Several types of canyon topographies and arrays of surface-breaking, as well as embedded cracks, are considered. Sequences of dynamic photoelastic fringe pattern and caustic recordings yield surface stress data and stress intensity factor data for practical application in various fields of engineering.
