dc.description.abstract | It is reasonable to apply crack closure concepts, i.e. roughness-induced crack closure, to understand the crack propagation behavior under mixed mode loading conditions. In this paper, the characteristics of fatigue crack propagation under mixed-mode loading is studied using the concept of roughness-induced crack closure, and a model of the variation of the crack opening ratio is proposed based on multi-variable statistics. In addition, fracture surfaces are examined by C-scan and classified into four stages to quantify the effect of crack closure. The roughness parameter based on the highest intensity reveals the effect of roughness-induced crack closure on the fatigue crack propagation. [doi:10.2320/matertrans.I-M2011839] | - |
