Abstract
The present study aims at identifying all the anisotropic elasto-plastic material properties from simple uniaxial tension tests performed in two directions on steel sheet specimens having a complex geometry. A digital image correlation technique is used for the full-field heterogeneous strain measurement. An appropriate elasto-plastic constitutive model is adopted. The virtual fields method (VFM) is used as an inverse procedure to determine the constitutive parameters, which are calculated using tensile test results obtained in rolling and transverse directions.
