Incidence of plane waves upon a fracture

WebThe objective of this paper is to reveal the details of the transmission and reflection of compressional and shear waves at arbitrary angles of incidence upon a planar fracture. … WebA theoretical model has been developed which predicts the amplitude and group time delay of the transmitted, reflected, and converted waves resulting from a plane wave incident upon a single fracture. It is assumed that seismic stresses are continuous across the interface. Seismic particle displacements, however, are assumed to be discontinuous.
