✦ Synopsis

Growth patterns of surface cracks in plates subjected to combined cyclic tension and bending are examined. Different methods of prediction of the aspect ratio variability of these surface cracks are compared with experimental data. The objective is to identify the most accurate method. The comparison is based on a quantitative criterion as well as on statistical examination of the level of agreement with the data. The solutions evaluated include both theoretical and empirical formulas. The comparison shows that it is possible to predict the aspect ratio variability with a standard deviation of less than 0.06.
