Evaluation of eq (14.12) gives 0m as a function of Kn/Kf. The result is shown in figure 14.14. Also shown are four data points of crack growth angles measured in mixed mode fatigue crack growth tests [23]. The measured angles agree very well with the criterion. The locus for fracture, as given by eq (14.18) is shown in figure 14.15. Results of tests on plexiglass [21] appear to show reasonable agreement with eq (14.18). According to Williams and Ewing [24], an improved correlation with test data is
