A fracture model of a blunt-notched brittle crack embedded in a plastically deformed ductile medium is developed. An elastic enclave separates the notched tip from the plastic zone that is generated by the dislocations created within this zone. Effects of the notch-root radius and material parameters on the fracture toughness are predicted. The predicted fracture toughness is consistent with experimental observations.
