✦ Synopsis

Different methods of prediction of the aspect ratio variability of growing surface fatigue cracks in tension plates 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. Fifty-eight cracks are analysed. The total number of data points is 450 taken from 20 references. The solutions evaluated include theoretical as well as empirical formulas. The comparison shows that it is possible to predict the aspect ratio variability with standard deviation <0.070.
