ISRM	Wave Propagation in Fractured and Cracked Media Working Group of the International Society for Rock Mechanics Commission on the Application of Geophysics in Rock Engineering
Working Group Members: Prof. Koichi Sassa Prof. Laura  J. Pyrak-Nolte Dr. Larry Myer Dr. Kurt Nihei Prof. Toshifumi Matsuoka Prof. Toshiki Watanabe	Prof. Koichi Sassa, chair of the ISRM Commission on the Application of Geophysics in Rock Engineering has appointed a Working Group to develop a series of articles on the application of seismic wave propagation to problems in rock engineering.  The main multi-year project of the working group is to write a review article and develop a website on wave propagation in fractured and crack media.  The goal of the article and the website is to provide an information source for ISRM members and others that contains (1) a comparison of theoretical and numerical models of wave propagation through fractured and cracked media, (2) important laboratory results from experiments on fractured and cracked media, (3) numerical models online for use, and (4) an extensive literature database.  If you would like to contribute information, a numerical or analytical model, a reference, experimental results or a link to your home page (example link), please contact ljpn@physics.purdue.edu.
