Analysis of the Stress Invariants Criterions for I-II Mixed Mode Crack Initiation Angles

Abstract:

Crack propagation in practical engineering problems is often of mixed-mode type. The analysis of mixed-mode I–II crack initiation angles under different loading conditions is presented using stress invariants criteria. Where I1 and I2 are the first and the second stress invariants, IP-criterion postulates that crack will propagate along the direction defined by a maximum value of IP along the elastic–plastic boundary defined by von Mises. The mixed-mode I-II crack initiation angle is predicted successfully and is agree well with experimental data.
