In the industrial forming of metal sheet or plate components a constant problem is the change of shape of the formed part under the elastic stresses that are released when the forming load is removed. In the present paper, we simplify the deep drawing process as a two dimensional problem. We consider the influences of tension, clearance between die and punch and die radius on the spring back and drawing forces neglecting variation of thickness and we compare the results with experimental ones.
It is found that, in the solution of spring back, in relatively small punch travel the theoretical results don't agree with experimental ones but in relatively large punch travel they are in good agreement with each other. In the drawing force, they are in relatively agreement with each other both small punch travel and large one.
