“…These predictions are consistent with the measurements performed by Parsons on 304L austenitic stainless steel [28]. intensity factor of a branched crack can be considerably lower than that of a straight crack with the same projected length [29]. For this reason, such a branching can retard or even arrest subsequent crack growth.…”

“…It can be seen in Figure 9a,b that, when the cracks in the composite material layer extend to the toughening layer, it mainly propagates along the bonding interface. Due to the well bonded interface, the crack width gradually decreases, indicating that the crack driving force is reduced and the crack tip is passivated [20,21,22,23]. Thus, the crack propagation is obviously hindered.…”

“…Using the configuration shown in Figure B‐I or Figure C‐I, the crack tip stress intensity factor K tip can be calculated by J tip with the following equation: Ktip=JtipE' where J tip is calculated with the following equation: Jtip=Jfar+Cinh=Jfarbolde0.30em·-0.10em()[ϕ]IFT〈〉Sboldnitalicdl=JfarJint where J far is the crack driving force J ‐integral loaded in the far field, C inh represents the interface material mismatch effect on crack tip driving force. The C inh is calculated by the J ‐integral around the interface, C inh = − J int , see Figure . In the present work, the nonlinear‐elastic J ‐integral J nlel is calculated for the J ‐integral here.…”

“…where J far is the crack driving force J-integral loaded in the far field, C inh represents the interface material mismatch effect on crack tip driving force. The C inh is calculated by the J-integral around the interface, 38 C inh = −J int , see Figure 12. In the present work, the nonlinear-elastic J-integral J nlel is calculated for the J-integral here.…”
