Original Abstract

The solution of stress intensity factorsat the front of cracks emanating from the notchesis a standard fracture mechanics problem. Values of stress intensity factors are greatly affected by anotch geometry. A special effort was engagedin determination ofthe dependence of the stress intensity factor on the crack length and the critical crack length corresponding to a vanishing influence of the notch in stress intensity factors calculations.The aim of this article is to verify the Lefort’s formula for the critical crack by another wayand to plot results in clear illustrative graphs.The Ansys finite element codewas used for various combination of both the total length of the notch/crack configuration and the notch radius of U-notchesto draw the attention to the effects of non-linear transformation of data during the data processing.
