The full field measurement technique has become a popular technique for the quick identification of complex and/or heterogeneous-in-space material behaviors. Based on the rich available corpus of information, this technique makes possible to identify complex evolution laws using few highly heterogeneous testing. Multiple techniques have been proposed up to now. Here, we detail the application of the constitutive error relation to the identification of linear elastic material models.Then, the natural extension of the constitutive equation gap method through a dissipation gap method is discussed for the identification of material behaviors involving dissipation. 2D reference examples are provided for each method. © 2012 EDP Sciences.
