RESONANCE INSTALLATION FOR TESTING FATIGUE OF MATERIALS AT HIGH TEMPERATURES (REZONANSNAYA USTANOVKA DLYA ISPYTANII MATERIALOV NA USTALOST PRI VYSOKIKH TEMPERATURAKH),
Abstract
In the apparatus described, a flat test-piece is secured at one end and caused to vibrate in resonance to electromagnetic excitation. The free end of the test-piece forms one plate of an air-dielectric condenser, the other being a fixed plate. The signal from this condenser is suitably amplified and recorded. At the first signs of failure the amplitude of the test-piece oscillation decreases, giving a sharp break on the recording. The test-piece is situated in a furnace with closely-controlled temperature. (Author)
