ABSTRACT:
The average strength or Young's modulus of the constituent particles of a sample is determined from the measured speed of sound propagated from a source through the sample to a receiver. Other sample data, such as the porosity, Poisson's ratio and the pressure applied to the sample, are also used in the determination. However, no data pertaining to individual particle sizes is required. The method provides a non-destructive test for the average strengths of materials such as iron ore pellets, alumina powder, silica flour, and coal dust.
