Paper Abstract

Four experimental methods for determination of dynamic mechanical properties of viscoelastic materials are presented. The first and the second ones are the strain and acceleration measurement at two different crosssections of an axially impacted rod specimen respectively. The third method adopts resonance technique and the fourth one is correction method. Tests are carried out with Nylon 6 and Polyurethane(pU) . The diagrams of complex Young''s modulus and loss factor versus frequency are obtained. Comparison shows that the results from these four methods are reasonably close. The useful frequency ranges for valid results for each method are discussed.
