Some implications of an elastic-plastic theory for the propagation of uni-dimensional compression waves in dry Ottawa sand are examined. The theory, which contains an explicit strain-rate effect, has previously been found to give good agreement with experiment. Results from it are compared with elastic and plastic theories of wave propagation in soils. Problems associated with the use and experimental determination of dynamic stress-strain curves are considered. Laws of similitude required by the present theory are examined. Tentative design data on the response of impact pressure gages are developed.
