| Abstract: | The velocity,stress and power fields are established along the maxi-mal variable direction of drawing velocity.The establishment of velocity field sati-sfies volume constancy.With approximate yielding criterion and boundary conditionat entrance,the differential equation of power distribution in deforming zone isobtained and solved.Let the power at exit be equal to external power the drawingstress is then determined |
