Damping coefficient material chart
WebThe index η E1/3 /ρ which measures the ability of a panel to damp flexural vibrations (η is the mechanical loss coefficient). High values of this index capture both high natural flexural vibration frequencies of metal foams (suppressing resonance in the acoustic range) and the ability of the material to dissipate energy internally. 5. http://abaqus-docs.mit.edu/2024/English/SIMACAEMATRefMap/simamat-c-dampingopt.htm
