摘要：The average strength or Young's modulus of the constituent particles of asample 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 ratioand the pressure applied to the sample, are also used in the determination. However, nodata 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, aluminapowder, silica flour, and coal dust.
