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...
