    Forging Reduction Ratio - Upset Before Reducing Area

    For calculate the reduction ratio you can use the following criteria: The constant-volume relationship in a cubic solid is expressed by: V1 = h1 . w1 . l1 V0 = h0 . w0 . l0 1 = h1/h0 . w1/w0 . l1/l0 applying ln 0 = ε1 + ε2 + ε3 = 0 ε1 = ln (h1/h0) ε2 = ln (w1/w0) ε3 = ln...
