摘要：
The identification of damage variables and their growth with loading in two dimensions by using only full-field displacement measurements has been proposed in this study. The equilibrium gap method is used to estimate the damage field during a biaxial experiment on a sample made of it composite material. From the analysis of a sequence of measurements, a proposed form of Constitutive law is tested and identified. The emphasis is put on the methodology that can be applied to a vast class of materials.
