✦ Synopsis

As can be proved from theoretical analysis, some mixed mode fracture criteria may be converted into an elliptical or ellipsoidal formula with the aid of mathematical translation. Others are of themselves an elliptical or ellipsoidal formula. Hence, on the basis of Griffith-Irwin theory, the paper suggests to take (K,/K,,)'+ A(KJK,,)* + B(KJK,,)* = 1 as the general criterion superseding all the mixed mode fracture criteria. A and B will be determined by the superseded criterion.
