A criterion for the prevention of split ends (alligatoring) is expressed mathematically. This criteria, t0 /R0 >1.81×(t0 /tf −1) is derived through the extension of an earlier upper bound solution for strip rolling of a perfectly plastic mises material. The treatment is based on the division of the deformation region to a series of triangles, undergoing rigid body rotational motions.
