Ten peer-reviewed papers cover the latest information on pendulum impact machines. STP 1476 represents the work of impact test researchers from around the world and provides input for further improvements in test methods, especially those used in construction codes and standards.
These papers are organized into four major areas:
Historical Developments in Impact Testingcovers the history and procedure development for Impact Testing
Impact Test Procedures and Machine Effectsdiscusses the effects on absorbed energy of removing and replacing an 8 mm Charpy striker
Reference Specimensaddress certification of Charpy reference specimens at IRMM, uncertainty analyses on reference values of Charpy Impact Test Specimens, analysis of Charpy Impact verification data, and much more.
Issues with Instrumented Strikersprovides different approaches for the verification of force values measured with instrumented Charpy strikers
