| Abstrakt: | Abstract: Five methods for determination of the resonant frequencies of the flexural vibration of a sample are shown. A simplified differential partial equation is used to estimate the values of the frequencies. For an unknown sample the Lissajous figure method as well as the method using different lengths of samples are most suitable. For samples with a known elastic behaviour a comparison of the fundamental mode and the 1st overtone frequencies can be used or a calculation of the resonant frequency from the dimensions and the known Young’s modulus can be made. |
