Abstract
A shear deformation apparatus comprises: a die having an inlet and an outlet; and a rotatable device installed at a shear zone for supporting a material introduced into the inlet of the die and thus changing a direction of the material to the outlet of the die, of which the surface moves together with the material. According to the apparatus, a frictional resistance between the material and the die is reduced and a generation of a dead zone is prevented, thereby reducing a deformation resistance and having a uniform shear deformation.
