Multistage deformation in sheet metal forming involves changes in strain path and strain rate. Strain path and strain rate variations affect work-hardening behavior and, the final useful strain before fracture. It is well known that an abrupt change in strain path may be accompanied by inhomogeneous deformations and unusual stress-strain curves. Wagoner and Laukoins analytically and experimentally studied two-staged uniaxial-biaxial tension and they identified two different patterns of work-hardening behavior in sheet metals, namely, ferritic-type and brass type. This paper presents a study of the influence of strain path on the yield strengths of two different ULC steel sheets exposed to uniaxial tension and biaxial deformations. The effect of initial and developed texture on the initial flow strength compared to monotonic flow strength is also presented.
