Finite element formulation and algorithms for unsaturated soils. Part II: Verification and application (2003, methodology): “The MCC model is again used to simulate the soil response, but the slope of the critical state line, M ; is now assumed to vary with the Lode angle in the deviatoric plane in accordance with a rounded Mohr–Coulomb failure surface [7].”
An interior‐point algorithm for elastoplasticity (2007, methodology): “On the material level the elastoplastic constitutive relations are integrated explicitly to within a specified tolerance and on the structural level an inexact Newton method, possibly enhanced by an error-based selection of the load step [16, 20–22], is used.”

Finite element formulation and algorithms for unsaturated soils. Part I: Theory (2003, methodology): “The performance of this adaptive time-stepping scheme has been tested on a wide range of elastic and elastoplastic saturated soil problems and, in all cases, it was able to constrain the global temporal error in the displacements to lie near the desired tolerance [33,34,36].”
