Abstract

The crack layer (CL) theory has the ability to estimate the slow crack growth (SCG) behavior on the basis of the theoretical background. This theory considers the interaction between crack and damages in front of the crack tip. It facilitates the reflecting damage mechanisms which appear different depending on the material. However, the applicability of this theory has not been investigated sufficiently yet, with regard to the various loading conditions. For this purpose, the critical CL parameters with the loading conditions must be specified. In this study, the discontinuous fatigue crack growth (FCG) tests with various loading frequencies are simulated by using CL theory. The two CL parameters are changed to fit the tests, and the relationship between loading frequency and CL parameters are constructed. It would be beneficial for industrial use of CL theory.
