The Force for The Plastic Deformation of One End of Round Bar Between the Dies with Dip Angle
Yin Jiyig(Department of Engineering)
The classic theoretical solution of the force for the plas- tic deformation of one end of round bar between the dies with dip angle has not been known up to the present. For this type of deformation, the author makes some suitable simplifications in two aspects: the geometrical shape and the distribution of the surface normal stress, and a mechanical model is established, On the basis of this mechanical model the author makes use of the (?)incipal stress method and Tresca yield condition to give a solution for this deformation and recommends a simplified method which can be used for engineering calculation conveniently.
