Stress-strain curves of AA1420, AA8090 and AA2060 sheet at (a) $\epsilon =0.001{\text{s}}^{-1}$ and (b) $\epsilon =0.01{\text{s}}^{-1}$ and different loading directions; variation in (c) flow stress, (d) ultimate tensile stress; and (e) Elongation to fracture% in relation of loading direction (0°, 30°, 45°, 60°, and 90° w.r.t. RD) for AA1420, AA8090 and AA2060 at $\epsilon =0.001$ & 0.01/s.
