The objective of this research is to develop a standard operating procedure for correlating uniaxial and biaxial digital image correlation (DIC) data and results from numerical finite element analysis (FEA) simulations to determine material elastic properties. An inverse method is developed in which iterative data matching is achieved using the software package, Isight™. The method is applied to characterize the elastic properties of Lexan polycarbonate sheet and a nominal carbon epoxy composite. Displacement and strain fields obtained from DIC data from simulated uniaxial tension and biaxial DIC experiments serve as the target parameter to match in iterative testing where the Young's modulus and Poisson's ratio are updated each cycle. The results of these experiments are used to verify that an accurate approximation of an unknown material's elastic properties can be predicted by this procedure.
