Three-dimensional stability limit analysis of cracked loess slopes

Rock and Soil Mechanics, 2022
The development of vertical cracks in loess slopes often affects slope stability. Compared with the plane strain mechanism, the slope stability analysis under the three-dimensional (3D) failure mechanism is closer to the actual slope instability.

Numerical simulation of the effect of weak shale bedding on fracture propagation through strata

Meikuang Anquan, 2023
Bedding strength is one of the key factors affecting the propagation of hydraulic fractures through beddings, which is mainly determined by cohesion, internal friction angle and tensile strength. However, there are few researches on this.

Butane dihedral angle dynamics in water is dominated by internal friction [PDF]

Proceedings of the National Academy of Sciences, 2018
Significance The interpretation of rates of reactions that take place in a solvent is complicated because of the entanglement of free-energy and history-dependent friction effects. In this context, the dihedral dynamics of butane has played a paradigmatic role since it is simple yet relevant for conformational transitions in polymers ...

Evaluating the Effect of Soil Particle Characterization on Internal Friction Angle [PDF]

American Journal of Engineering and Applied Sciences, 2021
One of the critical design parameters used in evaluating soil structure is the friction angle, derived from Mohr's Circle failure criterion. The soil friction angle is an engineering parameter estimated in the laboratory to quantify the soil shear strength in geotechnical applications. This paper indicates an experimental study investigating the impact

Upper Bound Finite Element Limit Analysis of Pullout Characteristics of Normal-Stressed Circular Anchor Plate

Geofluids, 2022
In this paper, the pullout factor and failure mode of circular anchor plate at an inclined angle with the horizontal ground under the normal stress are studied with the method of the upper bound finite element limit analysis. The effects of soil cohesion,

Failure Mechanism and Slope Factors for a Footing Resting on Slopes

Magazine of Civil Engineering, 2021
The behaviour of a footing affected significantly with the presence of the slope. The effect of slope on the bearing capacity, slope factor, and failure mechanism has been explored using limit analysis.

Effect of grain size distribution on the shear properties of sand

Frontiers in Materials, 2023
In this study, we investigated the effect of particle size distribution on the shear properties of sand. Direct shear tests were conducted using four types of sand samples with different particle size distributions obtained from standard sand produced by

Three-Dimensional Combined Finite-Discrete Element Modeling of Shear Fracture Process in Direct Shearing of Rough Concrete–Rock Joints

Applied Sciences, 2020
A three-dimensional combined finite-discrete element element method (FDEM), parallelized by a general-purpose graphic-processing-unit (GPGPU), was applied to identify the fracture process of rough concrete–rock joints under direct shearing.

Experimental Determination of Cohesion and Internal Friction Angle on Conventional Concretes

ACI Materials Journal, 2017
Various failure criterions have been used for the nonlinear analysis of concrete and reinforced concrete structures. To get more accurate results from the analyses, the selected failure criterion must be appropriate with the characteristics of problem and the assumptions made in the criterion should comply with the characteristics of problem.

Determination of soil shear properties on a soil to concrete interface using a direct shear box apparatus

International Journal of Geo-Engineering, 2017
Direct shear experiments were carried out both to investigate the interaction between a predominantly cohesion less soil and in-situ concrete and the validation of the tangent of two-third of the angle of internal friction angle normally assumed in ...
