    A critical review of the basic premises of fracture mechanics is presented. The applicability of the theoretical concepts developed by Griffith and considerably expanded by Irwin and co-workers to materials testing and the determination of a unique and characteristic value of “fracture toughness” is examined. Finally, the usefulness and limitations of sharp crack fracture mechanics to the solution of engineering design problems are discussed.
