The Pressure Vessel Research Council (PVRC) was formed as a part of WRC in 1945 to continue the mode of cooperative research relevant to improved design, fabrication, and reliability during World War II. Its goal was to coordinate and extend research on various aspects of pressure vessel technology under the direction of several Volunteer Committees.  It has made major contributions to the nuclear power and petroleum refining industries and the understanding and application of fracture mechanics.

The Materials Properties Council (MPC) was established in 1966 in response to the growing need for engineering properties and materials to support designers and life assessment.  MPC receives support from industry, technical organizations, codes and standards developers, and government agencies. MPC has compiled a record of notable progress with projects valued by electric utilities and petroleum companies.
