These programs have been distributed by Itasca Consulting Group, Inc. since their first commercial release in 1994. Initial development was partially funded by a consortium of companies for engineering applications ranging from largescale mine block caving to microscale powder compaction and sintering. The variety of applications of PFC has continued to increase in the 10 years since the first release of these programs. This volume contains a collection of 52 papers selected for presentation at the 2nd PFC Symposium, held 28–29, 2004, in Kyoto, Japan. These contributions cover a wide range of engineering applications and theoretical developments using PFC, and discrete methods in general. Topics include applications in civil engineering, slope and wall stability, rock fracture, shear flows, geology and industrial engineering. New developments are also described for contact bond models, fluid coupling and model calibration. This proceeding illustrates the great variety of PFC applications in different engineering fields, and includes case studies and general applications as well as research presentations. The volume should serve as a guide to help PFC users in their applications. We would like to acknowledge the contribution of CRC Solutions, Corp., Tokyo, Japan, especially Toshio Iwasaki, in hosting the 2nd PFC conference and assisting with the preparation of these proceedings. We also thank Michele Nelson who served as Technical Editor for the papers contained in this volume, and Chad Sylvain, who prepared the graphics illustration for the cover. Their assistance has been invaluable. Yoshi Shimizu Roger Hart Peter Cundall Editors
