Abstract
Various techniques for measurement of the dynamic mechanical properties of polymers are discussed. Special emphasis is given to the vibrating beam, SDOF resonance, SDOF impedance, creep, relaxation, forced oscillation (Metravib viscoanalyzer), and forced torsional oscillation (Metravib micromechanalyzer) techniques. Material property data, generated over wide ranges of temperature and frequency (using the above techniques), are presented in terms of reduced frequency upon application of an Arrhenius temperature‐frequency shift function. Comparison of these properties in the reduced frequency format indicates good correlation between techniques. Specific examples are included consisting of data generated from commercially available materials in both shear and tension‐compression states of stress from which estimates of Poisson's ratio may be determined.
