The International Society for Rock Mechanics (ISRM) was formed in 1962 as the only technical society devoted entirely to fostering the advancement of rock mechanics. In addition to sponsoring congresses and symposia, the Society undertakes its own scientific and technical studies, the results of which are published as commission reports.

United States interests are represented in the ISRM by a national group, the U.S. National Committee for Rock Mechanics (USNC/RM), which adheres to the Society on behalf of U.S. scientists, engineers, and technologists interested in rock mechanics. AGU is represented in USNC/RM by Terry Engelder (Lamont-Doherty Geological Observatory). One of the functions of the national group is to provide for individual memberships in the ISRM.
