Dynamic compressibility of clay and loam

Abstract
The results of investigation of dynamic compressibility of clay and loam at strain rate 10³ s ^{- 1} and higher are presented. At strain rate 10³ s ^{- 1} the experiments were carried out by using modification of Split Hopkinson Pressure Bar (SHPB), plate impact experiment was used at strain rate 10⁴ s ^{- 1} and higher. Shock adiabats were determined by reflection method. As the result of the experiments dynamic compressibility curves, hydrostatic curves and dependence of shear strength from pressure were obtained at uniaxial strain conditions. The joint use of these complementary methods has allowed to extent a range of loading conditions. The results obtained can be useful for formulation of equations of state for clay and loam.
