Normalized Stress-Strain for Undrained Shear Tests

Source

Normalized stress-strain curves are obtained by use of maximum shearing stress to normalize shear stress and reference strain to normalize shear strain. Reference strain is defined by initial tangent shear modulus and maximum shearing stress. This paper defines initial tangent shear modulus and maximum shearing stress to be functions of effective stress state. Consequently, the normalizing parameters vary with stress points along the stress path. An incremental procedure is established whereby normalized stress-strain curves can be obtained. These curves are relatively independent of effective stress path and are nearly identical to those obtained from drained tests. This method shows promise for correlating results from drained and undrained triaxial tests with results from other types of shear tests.
