Abstract
In the present investigation, the critical major strain in anisotropic sheet metal forming is calculated under three axial stress states. Plastic analysis is based on the modified Hosford yield criterion, the Levy—Mises stress—strain increment relationship, and the power law material constitutive equation. Results show that the critical major strain is usually insensitive to the Hosford exponent.
