Formulation of Anisotropic Strength Criterion for Geotechnical Materials

Advances in Civil Engineering, 2020
A new nonlinear unified strength (NUS) criterion is obtained based on the spatially mobilized plane (SMP) criterion and Mises criterion. New criterion is a series of smooth curves between SMP curved triangle and Mises circle in the π plane and thereby ...
