Abstract By investigating the criteria of slip initiation,fatigue fracture and surfacecrack propagation in a carbon tool steel under combined stresses, fatigue features of smoothand cracked specimens are discussed from the point of view of local stress. Results show that,for short cracks, linear elastic fracture mechanics is applicable provided that the nominalstress is smaller than the slip initiation threshold stress of the material, and the size of plasticzone around a crack tip is almost a constant regardless of the crack length and deformationmode under threshold condition.

Key words: fatigue threshold stress of crack propagation mixed mode tool steel
