A Surrogate Model for Stability Assessment of Two‐Layered Cohesive Slopes
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT This paper introduces a novel surrogate model for rapid stability evaluation of two‐layered cohesive slopes under undrained conditions. The model eliminates the need for iterative calculations and slip surface searches, allowing for fast and accurate stability assessments without reliance on advanced numerical tools. The formulation is derived

Numerical Modeling of Geological Fault Reactivation Using Sequential Coupling Strategies
International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.ABSTRACT The interaction between fluid flow and mechanical deformation in fault zones can lead to processes of fault reactivation, triggering potential geomechanical problems such as seismicity, well collapse, fluid migration to shallower layers, and aggravated surface subsidence.

The influence of out-of-plane stress on a plane strain problem in rock mechanics [PDF]
, 1987 This paper analyses the stresses and displacements in a uniformly prestressed Mohr-Coulomb continuum, caused by the excavation of an infinitely long cylindrical cavity.

A new smooth failure criterion for concrete inspired by Lubliner's condition
Structural Concrete, EarlyView.Abstract A new failure criterion with 10 parameters is proposed, based on Lubliner's idea of joining two Drucker–Prager cones. The novelty lies in the way of introducing deviatoric shape variation: through two Podgórski's functions. This feature allows for improving plane stress cross‐section's compatibility with experimental data.

Structural Concrete, EarlyView.Abstract This article examines the behavior of reinforced‐concrete pile caps on two piles under concentric and eccentric loading, with emphasis on the influence of horizontal and vertical supplementary reinforcement on load‐carrying capacity. Although the Strut‐and‐Tie method does not include this reinforcement in the internal equilibrium, it was found

Probabilistic landslide risk assessment: Case study of Bujumbura
MATEC Web of Conferences, 2018 A spatial probabilistic landslide risk assessment and mapping model has been applied in a data scare region. The probabilistic model is based on a physical model based on Mohr coulomb failure criterion.

Elastoplasticity Informed Kolmogorov–Arnold Networks Using Chebyshev Polynomials
International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 8, Page 3331-3354, 10 June 2026.ABSTRACT Multilayer perceptron (MLP) networks are predominantly used to develop data‐driven constitutive models for granular materials. They offer a compelling alternative to traditional physics‐based constitutive models in predicting non‐linear responses of these materials, for example, elastoplasticity, under various loading conditions. To attain the

A Piecewise Yield Failure Criterion including the Critical State for Brittle Rock
Advances in Civil Engineering, 2020 The critical state of rock is an important index for measuring the changes in rock characteristics. However, this state is not unique because of the different researcher assumptions.
