    Introduction The theory of plasticity has gained a wide application within constitutive modelling of soils. The Critical State Soil Mechanics (CSSM) framework developed by Schofield & Wroth in the 1960ies has proved a powerful basis for the development of elasto-plastic models for soils. One of the most popular models based on the CSSM concepts is the so-called modified CamClay model, which even today is available in most finite element codes for geotechnical analysis. Even though simple, the CamClay model is still able to capture the principle response of a soil sample subjected to various types of loading - drained or undrained - in the triaxial test apparatus. The model may thus be used to enhance the understanding of soil behaviour and serve as an introduction to elasto-plastic modelling of soils. Course objective The aim of this short course is to present a simple elasto-plastic model for soil and demonstrate the application of the model to standard laboratory tests in soil mechanics.
