heal.abstract	The variation of the direction θp of crack propagation in mixed mode with the angle β of the inclined crack is shown to fit very well to the variation of θr, of the bisector of the angle of directions θr1 and θr2 of max σr and sufficiently well to that of θrθ, bisector of the angle of directions θrθ1 and θrθ2 of min τrθ < 0 and max τrθ > 0. The variation of σcr/σcrI, causing initiation of propagation, with β as predicted by the max σθ criterion, fits very well to that of a critical loading evaluated by considering the combined ""opening"" effect of σ and τrθ along the circumference of a small circle centered at the crack tip. The above results may be used as criteria of mixed-mode fracture based on σr and τrθ. © 1986.	en
