This is a review of the failure criteria that have been proposed as smooth alternatives to Mohr-Coulomb. The surfaces are dealt with in a unified way by expressing them in terms of the equivalent Mohr-Coulomb friction angle. The latter is defined as the angle of friction of the Mohr-Coulomb surface that would pass through the particular point under consideration. This approach enables direct comparisons to be made between different failure criteria using a familiar soil mechanics parameter. It is shown that some criteria can lead to serious over- and under-estimations of the actual strength of soil, whereas others even contain singularities for certain stress paths. Details of the study are described and the conclusions drawn from the study are presented.
