Two-dimensional fracture mechanics problems for solids with sharp and rounded V-notches (2010, background): “In general case, for notched bodies under mixed mode loading only several fracture criteria have been proposed (Papadopoulos and Poniridis 1988; Seweryn and Mróz 1995; Dunn et al. 1997b; Hallström and Grenestedt 1997; Seweryn and Łukaszewicz 2002; Yosibash et al. 2006; Tovo et al. 2006; Berto et al.”
Numerical implementation of the coupled criterion: Matched asymptotic and full finite element approaches (2020, background): “[18] showed that the potential energy variations computed by both approaches for a sharp V-notch were close to each other (difference less than 1%) for small enough cracks, and that this difference was larger for larger cracks.”
Fracture assessment of U-notches under mixed mode loading: two procedures based on the ‘equivalent local mode I’ concept (2007, background): “Several criteria have been proposed to predict fracture loads of components with notches, subjected to mode I loading (See, for example Kipp and Sih 1975; Carpinteri 1987; Knesl 1991; Nui et al. 1994; Seweryn 1994; Gomez et al. 2000; Lazzarin and Zambardi 2001; Atzori and Lazzarin 2001; Strandberg 2”
