Abstract

Impact testing has become one of the accepted methods for determining toughness of a material or its ability to absorb energy during plastic deformation under multiaxial stress conditions. Although notch tension tests, and more recently, fracture toughness tests have become widely accepted, the requirement for notched-bar impact test data continues. Since toughness properties for most materials are temperature-dependent, impact tests at liquid-hydrogen and liquid-helium temperatures become important.
