Characterization of composite plates using the virtual fields method with optimized loading conditions

This paper deals with the direct identification of bending stiffnesses of thin homogeneous anisotropic plates. The idea is to determine the unknown parameters from a single test giving a unique heterogeneous strain field. For the purpose of identification, the virtual fields method (VFM) is used....
