title = "Material properties' identification using full field measurements on vibrating plates",
abstract = "The paper presents an experimental application of an inverse method leading to the identification of the elastic and damping material properties of isotropic vibrating plates. The theory assumes that the searched parameters can be extracted from curvature and deflection fields measured on the whole surface of the plate at two particular instants of the vibrating motion. The experimental application consists in an original excitation fixture, a particular adaptation of an optical full field measurement technique, a data preprocessing giving the curvatures and deflection fields and finally in the identification process using the Virtual Fields Method (VFM). The principle of the deflectometry technique used for the measurements is presented. First results of identification on acrylic plates are presented and compared to reference values. Results are discussed and improvements of the method are proposed.",
