Physical Review, 1928
A tubular specimen of the metal is made the elastic control of a heavy pendulum bar. The system can be set into forced vibrations, either bending or twisting the specimen, by a measured periodic magnetic force-couple. The resonance amplitude and frequency, with the moment of the impressed force-couple, yield the ratio of the energy dissipated in one ...

In recent decades the measurement of internal friction has been of valuable assistance for the acquisition of information on the behaviour of gas atoms and other interstitially dissolved atoms in metals. It can supply us with information on diffusivities, concentrations, terminal solubilities, surface reactions, precipitation phenomena, mutual ...

Internal friction in polyoxymethylene
Journal of Polymer Science, 1961AbstractMechanical relaxation was studied in bulk polyoxymethylene by means of a torsion pendulum. The magnitude of the large γ peak at 203°K. (for f = 1.1 cycles/sec.) decreases with increasing density. The magnitudes of the β peak at 260°K, and the α peak at 400°K. do not depend on density.

(1) The mean damping capacity of steel over a stress range of several hundred pounds per square inch is a physical property of the material, the value of which can be checked accurately by successive tests on the same specimen, with the apparatus and method developed in the course of this investigation.
