A stress scale in full-field identification procedures: a diffuse stress gauge
چکیده انگلیسی
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 identification technique, the sensitivity to noise and error in grid positioning is investigated numerically.
