A new criterion for fracture initiation

A new fracture initiation criterion is proposed in this paper which agrees with the results obtained by Theocaris and Andrianopoulos [ Engng Fracture Mech. 16, 425–432 (1982)] for the case of uniaxial, biaxial and shear loading at infinity. This criterion determines the critical radius and angular l...

Zusammenfassung:	A new fracture initiation criterion is proposed in this paper which agrees with the results obtained by Theocaris and Andrianopoulos [ Engng Fracture Mech. 16, 425–432 (1982)] for the case of uniaxial, biaxial and shear loading at infinity. This criterion determines the critical radius and angular location of the crack initiation in the case of ductile materials. The results are in very good agreement with experimental results reported in the literature.
