Impact Wave Propagation in Columns of Sand

Blaine Raphael Parkin

ResearchPublished 1959

A study of unidimensional compression waves in columns of sand. The medium is treated as an elastic-plastic continuum. It is assumed that each element of the substance exhibits as strain-rate effect such that, at a given strain, the plastic strain-rate is proportional to the difference between the compressive stress on the particle and that stress that would act on the element under static conditions. Published experimental results on the propagation of stress waves in sand are used as a basis of comparison between experiment and theory. The present theory gives satisfactory agreement with experiments on two dry sands.
