A.torsion pendulum for the determination of shear modulus and damping around 1Hz
article
A description is given of an instrument for the measurements of the dynamic shear modulus, G, and the corresponding damping, tanδ, of solid polymeric materials. The instrument is suitable for the measurement of moduli in the range from 106 to 1010 newton/m2, tanδ values from 0.005 to 3 and frequencies between 0.1 and 20 Hz. The temperature of the specimen can be adjusted to any value between −180 and + 300 ‡C. The obtained accuracy is better than 5%. The accuracy of the measurement considerably decreases when tanδ is higher than 0.3.
