Title: | An efficient experimental methodology for viscoelastic complex modulus identification |
Issue Date: | 2005 |
Abstract: | The numerical simulation of viscoelastic damping treatments requires a correctidentification of the complex modulus of the viscoelastic materials. In this work, a simple andaccurate experimental setup and methodology to identify the complex modulus of viscoelasticmaterials in shear are presented, tested and validated using commonly applied viscoelasticmaterials. The test system is based on the direct complex stiffness measurement. A numericalprocessing analysis is performed on the measured data in order to verify the validity of themeasurement and to construct the usual nomogram representation of the complex modulus. Thisdirect approach avoids the identification limitations of the vibrating beams technique usuallyapplied in the viscoelastic complex modulus characterization. |
