This paper extends the formulation of a recent yield and failure criterion [Mortara G. A new yield and failurecriterion for geomaterials. Géotechnique 2008;58(2):125–32] by modifying its shape in the deviatoricrepresentation. Such a modification improves the performance of the surface introducing a constitutiveparameter associated to the variation of the Lode angle. The criterion is validated through the comparisonwith experimental data obtained from multiaxial tests on soils, rocks and concrete. A special form of thecriterion will be also derived for numerical applications in order to remove singularities of the previouscriterion.
