In theoretical researches on the shearing process so far a rigorous plasticity theory could not be applied unless one made some assumptions which are not plausible. Because of its simplicity and easiness to realize the essential qualities of the process, the present research deals with the scissors type shear in which the kinematically and statically consistent slip-line solutions could be proposed. The slip-line analysis is carried out on the four stages in a process. Four kinds of the fields thus obtained can be joined each other without any abruptness. On the basis of the proposed fields the significance of the characteristic value in the deformation stated in the prior report was elucidated. Thus it has become possible to estimate the process of punch load as well as the width of contact zone.
