RELATIVE INFLUENCES OF STRESS PATHS WITH DIFFERENT INITIAL SOIL STATES ON STRESS ?STRAIN RESPONSE USING MODEL TESTS

It is now widely established that the behavior of s oils is described by elasto-plastic theories. The original elasto-plastic model was called the Ca m-clay model. Today there are numerous versions of elasto-plastic models, which are basically modifications or improvements over the original model. But the fundamental theory behind all these models is the same. Cam-clay (CC), Modified Cam-clay (MCC) and Wheeler are considered in the present investigation. These models are essentially based on critical state framework.
