Abstract In this paper, a novel discretization method in σ-τ space is developed to calculate
the upper bound limit loads and failure modes of anisotropic Mohr-Coulomb materials. To
achieve this objective, the Mohr-Coulomb yield criterion is linearized in σ-τ space, which
allows for upper bound solution of soils whose cohesion and friction coefficient varying
with direction. The finite element upper limit analysis formulation using the modified
anisotropic yield criterion is then developed. Several examples are given to illustrate the
capability and effectiveness of the proposed numerical procedure for computing rigorous
upper bounds for anisotropic soils. More >
