The plastic hinge position in a bent cantilever struck normal to its plane by a steady jet applied at its tip

Abstract The position of the plastic hinge in a cantilever, which is bent in its own plane at an angle less than or equal to 90°, (see Fig. 1), when struck normal to its plane by a steady jet force at its tip, is determined after assuming the pipe material to be rigid-perfectly plastic. Some numerical results are presented to assist in the discussion of pipe-whip problems.
