Abstract
A system is described to measure internal friction and creep of thin materials. The detection is based on the variation in
collector current with the capacitance of the tuned circuit of a tuned collector crystal oscillator. The mechanical systems
used to realize those measurements are described. A high sensitivity is obtained for the different modes of solicitation.
