   Abstract:
   To demonstrate that a worst-case crack, as defined by the greatest crack-opening angle, can exist elsewhere other than at the root of a cantilever beam, the authors consider a beam of length l and of mass per unit length m with an attached heavy tip mass M. For a given material with fully plastic yield momentum M_p, for a given crack size γ, and for a given input energy K, the total angle is clearly a maximum for minimum α, the rotor of the beam's rotary mass to the tip mass
