Abstract
Low carbon steel was deformed under double strain path changes consisting in three successive tension tests carried out in different directions with respect to the material symmetry axes. The influences of the strain amounts and severity of strain path change in the reloading yield stress and subsequent strain hardening were investigated in detail. The trends captured using the homogeneous anisotropic hardening approach, which is based on a homogeneous yield function, are in good agreement with the experimental results.
