Airy-based equilibrium mesh-free method for static limit analysis of plane problems

open access: yesVietnam Journal of Mechanics, 2016
This paper presents a numerical procedure for lower bound limit analysis of plane problems governed by von Mises yield criterion. The stress fields are calculated based on the Airy function which is approximated using the moving least squares technique.

Analysis of phase transitions in the mean-field Blume-Emery-Griffiths model [PDF]

open access: yes, 2004
In this paper we give a complete analysis of the phase transitions in the mean-field Blume-Emery-Griffiths lattice-spin model with respect to the canonical ensemble, showing both a second-order, continuous phase transition and a first-order ...

Method for calculating limit support pressure of face of shield tunnels considering principal stress axis rotation and soil arching effects in dry sand

open access: yesYantu gongcheng xuebao, 2023
For the deep-buried shield tunnels in dry cohesionless soils, it is critical to determine the support pressure acting on the tunnel face due to the significant soil arching effects.

Benchmark study of rock slope stability through Generalized Hoek-Brown criterion: case study of an open pit in Sudan [PDF]

open access: yesInternational Journal of Mining and Geo-Engineering, 2022
The non-linear Generalized Hoek-Brown (GHB) failure criterion for rock mass is widely accepted and has been applied in a large number of open pits slope designs. This paper proposes new equations for estimating the maximum confining stress from the (GHB)

Relaxation rate, diffusion approximation and Fick's law for inelastic scattering Boltzmann models [PDF]

open access: yes, 2008
We consider the linear dissipative Boltzmann equation describing inelastic interactions of particles with a fixed background. For the simplified model of Maxwell molecules first, we give a complete spectral analysis, and deduce from it the optimal rate ...

Limit Analysis and Limit Equilibrium Solutions in Soil Mechanics

open access: yesSoils and Foundations, 1970
ABSTRACT Idealizations in soil mechanics are usually necessary in order to obtain solutions and to have these solutions in a readily applicable form. Limit equilibrium has been a method of solving various soil stability problems. One weakness of the limit equilibrium method has been the neglect of the stress-strain relationship of the soil ...

Relation of Limit Equilibrium Method to Limit Analysis Method

open access: yesSoils and Foundations, 1991
The Limit Equilibrium Method (LEM) is an empirical technique, and the characteristic of its solution has not been clarified yet. The authors have been studying LEM in which slices or blocks are used to represent the sliding mass, and they suggested that LEM is a method which satisfies the necessary condition of Slip Line Method (SLM), because a block ...
