In compression the signal of ε1 is negative. If you adopt as positive the compression stress (usual sign convention) because of forging, you should write as: ε1 = - ln (h0/h1) For rounded bar: V = h0 . A0. you can use to calculate reduction rate and real deformation as: r (reduction) = (A0 - A1)/ A0 = 1 - A1/A0 = 1 - L0/L1.
