The International Conference on Fracture of Concrete and Rock was organized by the Society for Experimental Mechanics (SEM) subdivision on Fracture of Concrete and Rock and RILEM Committee 89-FMT Fracture MechanicS of Concrete; Test Methods. The venue was Houston, Texas on June 17-19, 1987 and cooperation was provided by ACI 446, Fracture Mechanics and RILEM 90-FHA Fracture Mechanics of Concrete; Applications. The conference co-chai rmen were Professor S. P. Shah, Northwestern Uni versity and Professor S. E. Swartz, Kansas State University with the able assistance of Professor K. P. Chong, University of Wyoming. The conference theme was Fracture Mechanics Applications to Cracking and Fracture of Concrete (plain or reinforced) and Rock Subjected to Uniaxial or Complex Stress States with Static- or Dynamic-Loading Rates. This theme was chosen in recognition of parallel efforts between the rock mechanics community and researchers working in the application of fracture mechanics methods to the problem of cracking and fracture of concrete.
