ENERGY COMPONENTS DURING THE TRIAXIAL CELL AND DIRECT SHEAR TESTS

The components of energy loss during a triaxial cell test are examined critically. It is shown that the stress dilatancy equation may be derived by inserting a modified cell pressure into the Bishop energy correction. The physical reason for this is discussed and the correct solution is derived in three different ways. In view of this correlation with previous thought the components of the Roscoe energy balance are discussed. The stress dilatancy equation for the triaxial cell extension test is also dervied, making use of energy components. The expression for the rate of internal work absorbed in friction due solely to dilation in a direct shear is shown to be similar in form to that in the triaxial cell test.
