Abstract

This paper presents an identification method for five bending stiffnesses of symmetric laminates using the vibrational characteristics. A rough value of bending stiffnesses is first estimated using the five lowest pairs of eigenfrequencies and eigenmodes. Then the estimation of bending stiffnesses is improved by minimizing the difference between the measured and calculated eigenfrequencies. The effect of the measurement errors on the identification results is also discussed.
