Upper: map of real and imaginary parts of the structural parameter of an aluminum plate with an added patch of adhesive damping material identified with CFAT [51]. Lower: equivalent flexural rigidities (D _{i j} ) of an anisotropic honeycomb sandwich panel identified with CFAT on wide frequency band D ₁₁ ([rgb]0, 0.45, 0.74 –), D ₂₂ ([rgb]0.67, 0.08, 0.18 –), D ₁₂ ([rgb]0.47, 0.67, 0.19 –), D ₁₆ ([rgb]0.93, 0.69, 0.13 –), D ₂₆ ([rgb]0.49, 0.18, 0.56 –), compared to predicted values (equivalent homogeneous thin plate model) in dashed lines [52].
