RESPONSE OF GRANULAR SOIL ALONG CONSTANT STRESS INCREMENT RATIO PATH

This paper establishes, experimentally, the stress-strain response of a granular soil along a wide range of constant stress increment ratio paths for the condition of sigma-sub-2 = sigma-sub-3. Emphasis is placed on the investigation of the influence of rho on plastic strain increment ratio and the 'small strain' behavior. It is shown that the strain recovered during unloading along a constant sigma-sub-3 path can contain a significant plastic component. However, the response for unloading along a constant R path is essentially elastic although anisotropic in nature. A cross-anisotropic elastic model, with the degree of anisotropy increasing with R, is proposed to model the elastic resoponse.
