An analytic solution is given for intersonic mode II crack acceleration. The solution is obtained by first considering a self‐similar problem, motion of a semi‐infinite crack at constant velocity, under the action of a constant crack face load, appearing behind the crack edge. This solution is then repeatedly used in a superposition scheme, which finally yields the solution for an accelerating crack.
