Determination of physicomechanical properties of soft soils from medium to high strain rates

A method is presented for obtaining materials parameters, for quartz sand, over a wide range of strain rates. This involves the use of a modified Kolsky bar and plate impact experiments. Data were analysed based on the determination of longitudinal and lateral stresses in the Kolsky method. These values were combined with the longitudinal stress data from shock experiments to provide a stress–compression curve. From this curve, other parameters can be determined.
