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.

Strength model of a cemented body based on self-compacting characteristics of tailings
Frontiers in Earth Science, 2023 To examine the strength and mechanical characteristics of self-compacting tailings, a direct shear test was conducted under various consolidation states and moisture contents to determine the cohesion and internal friction angle of the tailings.

Comparison of Internal Friction Angles of Soils for Foundation Engineering
IOP Conference Series: Earth and Environmental Science, 2016 The aim of the publication is to evaluate the indicative modules of the deformation of fine-grained, sandy and gravelly soils. Deformation modulus is one of the most important geotechnical properties in terms of geotechnics. The reason is that it is most important from the point of assessing subsidence of buildings and expresses the characteristics ...

Numerical Simulation on Borehole Instability Based on Disturbance State Concept
Energies, 2022 This paper carries out a study on the numerical simulation of borehole instability based on the disturbance state concept. By introducing the disturbance damage factor into the classical Mohr–Coulomb yield criterio, we establish a finite element hydro ...

Active State Earth Pressure based on Dubrova’s Method of Redistribution of Pressure
Electronic Journal of Structural Engineering, 2018 Modes and magnitude of wall movement have great influence on the distribution of earth pressure behind retaining wall. For gravity retaining wall exerted by cohesionless soil rotating outward about the base, based on Dubrova’s method of redistribution ...
