In this study, an inverse analysis method for determining the material properties from measured displacements for a power-law hardening material is proposed. Displacement distributions on a specimen surface under load are measured using digital image correlation. The virtual fields method combined with the total strain theory is used as a method for inverse analysis. The effectiveness of the proposed method is demonstrated by applying to aluminum specimens under three-point bending. Results show that the material properties after yielding can be identified from the displacement fields by the proposed method.
