Abstract

A method for determining crack-growth resistance curves previously proposed by the author is derived from fundamental relationships. Data are presented that further demonstrate the application of the method to materials having a wide range of properties. It is concluded that the use of this method results in obtaining fracture properties not previously measured directly.
