Abstract (EN): This work is devoted to the analysis of the static and dynamic properties of composition corks used as damping cores in sandwich structures. A mixed displacement-stress beam finite element is formulated, implemented and used as a valuable numerical tool in an inverse identification methodology, where the core material is characterized from the free vibration response of the sandwich beam. The obtained values for the storage modulus and loss factor are compared to the static Young's modulus identified from an experimental characterization analysis using compression and tensile tests.
