A stress scale in full-field identification procedures: A diffuse stress gauge

Résumé

Identification techniques solely based on displacement field measurements lack a stress scale and thus require a complementary information to be provided to complete the problem definition. Such a complementary test is proposed in this study, which is itself an identification designed for an unbounded two dimensional domain subjected to a normal point force on its boundary. A complex potential formulation is used to obtain a simple closed-form solution for the Poisson's ratio and Lamé's shear modulus. In order to evaluate the performance and robustness of this identifi- cation technique, the sensitivity to noise and error in grid positioning is investigated numerically.
