Three dimensional deformation laws for a sand clay

The paper begins by briefly summarising the theoretical and experimental criteria for evaluating consummate constitutive relationships for soils. It is demonstrated that such relationships necessarily include parameters reflecting the influence of the intermediate principal stresses and strains. A newly developed true triaxial apparatus is then described. The remainder of the paper is concerned with an experimental investigation of the response of a sand clay to repeated true triaxial loading with particular emphasis on the role of the intermediate principal stress expressed in terms of the lode parameter. The response of the soil is evaluated in terms of elastic models whose constants of compliance and stiffness were calculated using statistically orientated methods. The experimental results demonstrated that changes in the lode parameter had a marked influence on the constitutive relationships.
