Analytical solution of stress-strain relationship of modified Cam clay in undrained shear
Vincenzo Silvestri and Ghassan Abou-Samra

 
Abstract
    The modified Cam clay (MCC) model is used to study the response of virgin compressed clay in undrained compression. The MCC deviatoric stress-strain relationship is obtained in closed form. Elastic and plastic deviatoric strains are taken into account in the analysis. For the determination of the elastic strain components, both a variable shear modulus and constant shear modulus are considered. Constitutive relationships are applied to the well-known London and Weald clays sheared in undrained compression.
 
Key Words
    modified Cam clay model; constitutive relations; elastic and plastic deviatoric strains; virgin compressed clay; undrained compression; comparisons.
