โฆ Synopsis
Digitized data on crack growth of corner cracks at holes in a plate loaded in tension were published by Grandt and Macha. Empirical stress intensity factors were derived from these data. The empirical values were compared to stress intensity factors obtained by interpolation between calculated data of Raju and Newman. A satisfactory agreement was found.
