|Summary||This paper deals with the experimental identification of parameters governing the elastic properties of composite plates. The approach is based on the processing of the heterogeneous strain fields which are provided by well chosen mechanical tests. These fields are measured by particular optical setups developed in-house and are briefly described herein. The identification procedure itself is based on a specific use of the principle of virtual work. Examples of measurements of in-plane, bending and through-thickness stiffness components illustrate the approach.
||Keywords|| full-field measurements, identification, mechanical characterization, optical methods, principle of virtual work.
