Abstract
This study concerns the identification of complex stiffness components (ie, stiffness and damping) on isotropic vibrating plates. One of the main difficulties in damping measurements comes from the connection of the specimen to its environment (joints, clamps etc…) causing extra energy dissipation. The present procedure based on full field slope measurements from a deflectometry set up together with an inverse identification technique called the Virtual Fields Method is capable of identifying the material damping regardless of the dissipation coming from the specimen boundary conditions. This paper will present some experimental results confirming this statement.
