Failure lines for different criteria and location of critical points for DTT and FT. Failure lines for the different failure criteria in a planar stress condition (σ 2 = 0) in a plot of maximum principal stress σ 1 against minimum principal stress σ 3 , for a hypothetical brittle material with TS = 100 MPa and CS = 300 MPa, together with the location of the critical points for DTT and FT with the different failure criteria.
