Introduction

This example simulates a series of triaxial tests that can be used to verify that the Modified Cam Clay constitutive model is functioning properly. The simulations include:

1. Consolidating the sample to an initial isotropic stress state;
2. A drained strain-controlled test;
3. An undrained test on overconsolidated soil;
4. An undrained strain-controlled test; and
5. A load-unload-reload test.

The verification includes comparisons with hand-calculated values and discussions relative to the Cam-Clay theoretical framework.
