Size and geometry also plays a role in determining the shape of the R curve. A crack in a thin sheet tends to produce a steeper R curve than a crack in a thick plate because there is a low degree of stress triaxiality at the crack tip in the thin sheet while the material near the tip of the crack in the thick plate may be in plane strain. The R curve can also change at free boundaries in the structure. Thus, a wide plate may exhibit a somewhat different crack growth resistance beha…WebDec 27, 2024 · The small-notched specimen has the highest-initial-triaxiality (1.68) of all the geometries (Table 1) which, when combined with dynamic strain-rates, results in a …WebFigure 8: Crystal plasticity derived simulations of stress-strain curve (a) and stress triaxiality 13 (b) at the location of the five voids indicated in Fig. 5.
