Abstract: A method for measuring crack propagation in samples as a function of the number of load cycles is proposed wherein changes in the frequency response of a mechanical impedance of a sample which is to be tested is registered. At a pulsation frequency, which corresponds to the resonant frequency of the sample, there is a rise in the resonance of the mechanical impedance, defined as the quotient of the speed of movement of the sample and the applied pulsating force. Since, when a crack grows in the sample, its elastic constant decreases along with the cross-sectional area, the frequency response of the sample shifts towards lower frequences.

Abstract: An inexpensive, non-obtrusive optical flowmeter is disclosed comprising at least one flexible, light transmitting optical fiber rod having an enlarged (e.g. spherical) terminus formed at a fluid responsive end thereof. The flexible optical fiber is inserted into a fluid channel in such a manner that the enlarged terminus oscillates at a frequency that is a function of the rate of fluid flow. The intensity and frequency of an optical signal being transmitted via the optical fiber to an optical detector are related to the rate at which fluid flows through the channel.

These oscillations are converted into corresponding electrical signals by a pair of transducers coupled to opposing ends of the spindle to provide two independent outputs.
