Abstract：

Mechanics model on bending deformation of the blank through the die radius in the process of the drawing for the circular(cone) shell has been established on the base of Calladine's model.The binding of blank holder on the blank has been considered in the model.Theoretical analysis and test result illustrate that the model established by the paper is valid and the analytic results of the formulate by the paper show a good agreement with the experiments for circular shell within the limits of rational value of the die radius.Law of the normal stress on the section located at the exit of the die radius is analyzed in the process of the drawing for the circular(cone) shell.The theoretical formulate of the law of this normal stress is given.
