WebWith increase in loading, the crack-tip bifurcation mechanism was observed (Fig. 6.7E and F). These features support the presence of MWCNT networks that can contribute to the ductile nature of nanocomposites. This was also reflected from the necking behavior of nanocomposites such as CN1 (16), CN3 (12), and CN3 (16) (Fig. 6.7D–F). WebFurthermore, as shown in Fig. 5h, crack bifurcation occurred when the propagation path was blocked by carbides or attracted by micropores; however, the propagation mode was dominated by a...
