Abstract
Abstract Constitutive models for geomaterials are frequently developed and calibrated on the basis of element tests. Prior to the analysis of element tests a suitable set of work-conjugated stress and strain measures has to be selected. The paper points out that the traditional analysis of triaxial tests is theoretically inconsistent as finite and infinite strain measures are mixed in the analysis. Therefore, two theoretically consistent methods are proposed and examined for the analysis of triaxial tests. These three methods affect strain-dependent material parameters differently. The effect is analysed using key geotechnical parameters and an advanced constitutive model.
