Abstract

Summary

We introduce the fracture-layer according to Schoenberg theory and insert this layer into a periodically layered elastic medium. The low frequency dispersion due to the presence of fractures and/or layering is defined. In weak-contrast approximation, the elements of sensitivity matrix illustrate the pure- and cross-effect of both fracturing and layering.
