TLDR
In this article, a Mooney Viscometer and an Oscillating Disk Rheometer are used to measure the visco-elastic properties of rubber and rubber-like materials.Abstract:
The invention comprises a device which performs the functions of both a Mooney Viscometer and an Oscillating Disk Rheometer to measure the visco-elastic properties of rubber and rubber-like materials Rotational and oscillating motion are transmitted to a shaft by means of a sprocket and a hub connected to an eccentric Rubber samples having a wide range of stiffnesses can be accommodated by a provision for changing the thickness of the sampleread more

Method and instrument for viscoelastic measurements
TL;DR: In this article, an apparatus for measuring viscoelastic properties of rubbery materials is described, which comprises two opposed dies having temperature and pressure controling means, means for initiating oscillatory rotation of one of the dies whereby the sample is cooled during its residence between the dies and reheated whereby torque measurements are carried out during the period of cooling.

Methods and apparatus for measuring the viscoelastic response of vocal fold tissues and scaffolds across a frequency range
TL;DR: In this paper, the authors used torsional waves to measure the mechanical properties of vocal fold tissue and candidate materials for use in human vocal fold reconstruction, and the experimentally determined amplification factor is obtained as the ratio of the amplitude of the rotation of the top plate divided by the corresponding amplitude of bottom plate, which is then obtained from the experimental data gathered by the apparatus.

Oscillating rheometer die set
TL;DR: In this article, an oscillating rheometer die set is described, with modifications to the lower die apparatus, the upper die apparatus and the oscillator head, such that the elastomer sample is not encapsulated and once cured, may be easily removed from the cavity.
