A microscopic mechanism that causes this phenomenon is called microvoid coalescence, and in one regime, the strain energy release rate caused by this process is equal to the J integral. The "conchoidal" type of this phenomenon begins at a swelling called the "bulb of percussion". Considering the surface-energy increase caused by this process leads to a derivation of Griffiths' criterion for it. This phenomenon occurs in three different modes: opening, in-plane, and out-of- plane. This phenomenon is marked by an X on the end of a stress-strain curve, and it happens more easily in brittle materials than ductile materials. For 10 points, name this phenomenon in which an applied stress causes a material to break in two.
