Investigations of the effect of cold working on the
internal friction of copper have become numerous in the last
few years due to the discovery that part of the internal
friction is due to the motion of dislocations in the metal.
Most of the investigations so far have been done...
This investigation represents a previously unreported method
of measurement of internal friction in single crystals of silicon. The
method consists of exciting a rectangular reed of silicon of uniform
cross section into forced vibration at its resonant frequency. The end
of the reed is silver plated and eddy currents induced...
The capacity of a vibrating solid to convert its mechanical energy of vibration into heat is called internal friction. Its most common manifestation is the damping effect which causes loss in vibration amplitude of a freely vibrating solid. The damping is a result of the anelastic behaviour of materials. This...
