Abstract
A simple apparatus for determining the dynamic properties of elastomers in shear at audio frequencies is appraised. Typical values of shear modulus and viscosity for several elastomers are given, both at room conditions and at 150 F. The frequencies of test range from 100 to 5250 cycles per second, the shear moduli from 0.5 × 106 to 480 × 106 dynes per sq cm and the viscosities from 20 to 75,000 poises.
