E. Maggiolini et alii, Frattura ed Integrità Strutturale, 33 (2015) 183-190; DOI: 10.3221/IGF-ESIS.33.23 187 Graph 1: Tendency of the position in the horizontal notch. Graph 2: Tendency of the position in the inclined notch With regards to the trend of the maximum value of σ eff,IG as a function of H/c, a trend very similar to that reported in [18] is seen, whereby it does not depend on the notch height, but on the lateral V-notch opening angle. Graph 3: Trend of σ eff,IG depending on the opening angle in [18] (left) and on H/c (right) In both cases, σ eff,IG rises until it reaches its maximum level (located at 2α=60° and H/c=0.05), before falling back down to the minimum. Second set of geometries As concerns the notched geometries with radius, σ 1 does not reach its maximum in the point where the fillet starts, but it moves in the curvilinear part of the notch as shown in Fig. 7.
