Abstract
We review here the constitutive compatibility method for the identification of local elastic parameters based on full-field measurements. In this method, the statically admissible stress field that can be related through the known constitutive symmetry to the kinematic observations is sought through minimization of an objective function which measures the violation of constitutive compatibility. After this stress reconstruction, the local material parameters are identified with the given kinematic observations using the constitutive equation. The method has been adapted to solve larger identification problems using a domain decomposition technique which allows for reduced computational load and higher identification accuracy within subdomains.
