Abstract : Although the characterization of crack stability is an important attribute of this specimen and the one which this paper treats, other desirable features are noted. Multiple toughness determinations can be obtained in a single specimen. The control of pop-in lengths and the accompanying velocity changes poses further the possibility of using this specimen for study of strain rate effects on toughness and for studying the dynamics characteristics of crack propagation.
