On the determination of the stress-strain curve of clay from the undrained plane-strain expansion of hollow cylinders: a long-forgotten method

摘要

This paper presents the method to obtain the shear stress curve of clay from the undrained plane-strain expansion of hollow cylinder triaxial tests. No prior knowledge of the constitutive properties of the material is required. The theory also indicates that when die outer radius of the cylinder is very large compared with the inner radius, the equation used to interpret pressuremeter tests ir clay is recovered.
