Properties of granular packings under low amplitude cyclic loading
Abstract The initial tangent and the secant moduli for granular materials under low amplitude cyclic loading is obtained from an analytical model considering particle interactions. The Hertz-Mindlin theory of contact of two elastic spheres are used to describe the contact displacement behavior under oscillating forces. The analytical model includes the effect of the void ratio, the coordination number, the constituent particle properties, and the structural anisotrophy. Results computed from the derived relations are compared with the experimental measurements for initial tangent and secant moduli.
