APPLICABILITY OF MOHR-COULOMB & DRUCKER-PRAGER MODELS FOR ASSESSMENT OF UNDRAINED SHEAR BEHAVIOUR OF CLAYEY SOILS

Properties of soils and the techniques to determine the same are very much dependent on the local geological conditions and the environment. Th e scope of the present study includes understanding the model predictions from classical constitutive models such as Mohr-Coulomb & Drucker-Prager. These models are widely used despit e availability of advanced models vowing to simplicity and easily determinable model parameters . An attempt has been made to present the formulation of the stress integration procedure for Mohr-Coulomb and Drucker-Prager models with associative yielding condition by using the incremental plastic theory which is a conventional and convenient practice in drawing stress paths.
