This paper describes the process of mechanical characterization of orthotropic materials. An hybrid approach based on the combination of phase-shifting electronic speckle pattern interferometry (PS- ESPI) and finite element analysis is utilized. Three-point-bending experimental tests are carried out. The difference between displacement values measured with ESPI and their counterpart predicted by FEM analysis is minimized in order to find the values of the unknown elastic constants.
