DOI: 10.1007/s11340-017-0301-3
Abstract: The contact behavior for geological materials, such as reservoir shale rock, is simulated using the finite element method by considering a nano-indenter tip indenting into a geomaterial obeying the Mohr-Coulomb failure criterion. The deformation and… read more here.

DOI: 10.1016/j.jrmge.2018.04.002
Abstract: Abstract In this paper, the Mohr-Coulomb shear strength criterion is modified by mobilising the cohesion and internal friction angle with normal stress, in order to capture the nonlinearity and critical state concept for intact rocks… read more here.

DOI: 10.1038/s41598-019-49085-1
Abstract: The Mohr-Coulomb (M-C) stress criterion is widely applied to describe the pressure sensitivity of bulk metallic glasses (BMGs). However, this criterion is incapable of predicting the variation in fracture angles under different loading modes. Moreover,… read more here.

DOI: 10.1061/(asce)gm.1943-5622.0002154
Abstract: Abstract Using the classical (linear) Mohr–Coulomb (M–C) failure criterion, the failure mechanism of slopes is commonly treated as a completely shear failure. However, the tension failure mechanism... read more here.
