Numerical Modeling of Wave Propagation in Anisotropically Microcracked Media

摘要

A generalized self-consistent method (GSCM) is used to evaluate the effective moduli of a cracked medium and the wave propagation speed within this medium. Since the microcrack damage will in general have an angular distribution, the wave speed will be anisotropic. Furthermore, since cracks respond differently under tensile and compressive loads, waves propagating through the medium under different loading conditions will experience different wave speeds.
