AISI 302 stainless steel anodized bar (K = 1300 MPa, n = 0,30) square section 10 x 10 (mm) must be reduced by drawing / drawing end product 2x2 (mm).
(a) Prove that the maximum sectional reduction in the total stamping material is given by the relationship:
(b) is it possible to achieve the required reduction in a pass?
(c) if not, select a series of steps to achieve the desired reduction.
Ignore friction and mechanical properties change during successive passes
