Prediction of shape change of corner crack by fatigue crack growth circles

[Display omitted] •We develop an efficient new technique for predicting the shape change of a crack.•The crack growth is perpendicular to both the current and next new crack front.•Stress intensity factors are interpolated from the values in the database.•Accurate results can be obtained with much f...
