Abstract
Polymers with characteristic dissipation properties are obtained by compounding them with additives. The mechanical behaviour under vibration conditions of these compounds are characterized by dynamic moduli, which depend on the static preload. The test results of an PU-Compound is presented in this paper. The obtained results enable to calculate the complex moduli of a special dynamic constitutive equation, which then enables to calculate stress and strain of dynamic deformations of structures under static preload.
