Such work included for example, methods for determining the strain hardening exponent n, the anisotropy-values (lankford coefficient), as well as other tests for sheet metal formability and, later, forming limit diagrams.
The reason for these closed sessions was to allow experts to informally review critical issues related to materials, tests, and processes.
Typical topics include machinery and press tools, new processes, new materials, experimental methods for evaluating formability and studying press operations, springback, constitutive equations, plasticity criteria, and friction and wear with attention to interface behavior as characterized by topography and surface chemistry, lubrication, speed, and temperature.
Specific responsibilities of vice-presidents are to contact and represent the National delegations in their geographic area and to chair technical sessions at conferences.
Member countries include: Australia, Austria, Belgium, Brazil, Canada, Czech Republic, China, Denmark, Finland, France, Germany, Hungary, Italy, Japan, Luxembourg, Netherlands, Norway, Portugal, Slovakia, Slovenia, South Korea, Spain, Sweden, Switzerland, and the United States.
