The fluid flow in a sharp, propagating crack is shown to have a large pressure drop near the tip for finite crack velocities. An analysis of the effect of liquid surface tension is made to determine the possibility of cavitation of the liquid. The analysis indicates that cavitation is possible for certain liquid metal embrittlement systems. Other systems apparently cannot support cavitation, but the fluid flow will still be important since it influences mass transport within the propagating crack.
