Wave transmission in Hostun sand: multiaxial experiments

cubical cell which is being used to study the multiaxial stiffness of dry Hostun sand. The elements can be used to track wave transmission in both shear and compression modes both across from one side to the opposite side of the cube and diagonally from one side to an adjacent side and thus to deduce the elements of the cross-anisotropic stiffness matrix of the sand. Practicalities of the bender installation reduce the degree of redundancy in these deductions. An assessment of the evolution of elastic anisotropy under axially symmetric stress conditions is presented.
