Abstract
Abstract
The measurement of the dynamic bulk modulus of elastomers by the direct method using ESPI has been achieved within the frequency range of 50–1000 Hz. The two types of Nitrile rubbers tested show that the dynamic bulk modulus increases with frequency, but the rate of increase depends on the type of rubber used. A novel method of measuring the phase angle using ESPI was successful in principle, although the resolution error on the oscilloscope prevented definite conclusions being reached regarding its variation with frequency.
