Instrumented Charpy Impact Tests at Low Temperatures for Several Steels
Instrumented Charpy testing is recently of interest to study the impact property and fracture toughness of materials, and the standardization of the test procedures is currently discussed for the pressure vessels of power reactors.1 The instrumented impact testing system consists of an instrumented tup with strain gages to sense to compression loading, a dynamic transducer amplifier and a signal recording and display device. Such a system enables us to get load-time curves associated with fracture behavior of the test specimens.
