Discovering a generalized criterion that can predict the mechanical failure of various different structural materials is one of ultimate goals for scientists in both material and mechanics communities. Since the first study on the failure criterion of materials by Galileo, about three centuries have passed. Now we eventually find the "generalized energy criterion", as presented here, which appe...

While post-grouting is frequently reported to improve the engineering performance of piles, shear strength soil around piles not well understood. To investigate strengthening mechanism with permeation grouting, laboratory tests were carried out on homemade cement from aspects and microstructure characteristics. The evolution rule stress–shear displacement curve grouting different contents was a...

Sometimes it is difficult to choose the most appropriate failure criterion for problem analyzed. For brittle materials, attention must be paid availability of experimental data and calibration representative parameters, within chosen criterion. The work herein presented, starting with an overview on machromechanical criteria, analysed in Haigh-Westergaard Stress Space, investigates suitability ...

This paper presents a three-dimensional slope stability limit equilibrium solution for translational planar failure modes. The proposed uses Bishop’s average skeleton stress combined with the Mohr–Coulomb criterion to describe soil strength evolution under unsaturated conditions while its formulation ensures natural and smooth transition from saturated regime vice versa. analytical is evaluated...

The purpose of this paper is to study the solutions to the Signorini problem with Coulomb friction (the so-called Coulomb problem). Some optimal a priori estimates are given and a uniqueness criterion is exhibited. Recently, nonuniqueness examples have been presented in the continuous framework. It is proven, here, that if a solutions satisfies a certain hypothesis on the tangential displacemen...

In this research, the variation of ultimate bearing capacity, failure mechanism and deformation pattern of soil beneath two closely square footings have been studied using numerical methods. It is assumed that the adjacent footings are constructed on the surface of sand. The presented numerical analyses are based on explicit-finite-difference code, FLAC3D. The elasto-plastic behavior of soil is...
