    Over 60 papers present current thinking and research results behind procedures for characterizing the fracture toughness of materials, predicting safety margins against fracture, and predicting fatigue crack growth. Areas of emphasis include ductile-to-brittle transition, mircomechanisms, crack arrest, and sub critical crack growth.
