Effect of granular shape on angle of internal friction of binary granular system

Fuel, 2015
Abstract The study of angle of internal friction (ΦI) is widely prevalent due to its importance in science and engineering, and yet the quantitative description concerning the effect of granular shape on the ΦI is few. In our study, the influence of granular shape on the ΦI of various binary granular systems was investigated theoretically and ...

A summary of Viking sample‐trench analyses for angles of internal friction and cohesions

Journal of Geophysical Research: Solid Earth, 1982
Analyses of sample trenches excavated on Mars, using a theory for plowing by narrow blades, provide estimates of the angles of internal friction and the cohesions of the Martian surface materials.Angles of internal friction appear to be the same as those of many terrestrial soils because they are generally between 27° and 39°.

Experimental Research on Cohesion and Internal Friction Angle of the Double‐base Propellant

Propellants, Explosives, Pyrotechnics, 2013
AbstractA conventional triaxial confining pressure test was designed to suit the working environment of propellant grain. The mechanical properties of the double‐base propellant under varied confining pressure conditions were studied and analyzed. The results show that confining pressures have a pronounced influence on the mechanical properties of ...

Internal Friction Angles: Characterization Using Biaxial Test Simulations

1997
The internal angles of friction for cohesionless assemblies of particles under compression were determined using molecular dynamics type simulations of biaxial tests. The objective was to determine appropriate internal friction angles to be used for continuum modelling of broken ice covers on waterways.

Implications of thermal sensitivity of the static internal friction angle

2009
Thermal variability of the coefficient of the critical state, or the angle of internal friction is examined in view of experimental results obtained for clays and hard rocks. This sensitivity has several implications for the evolution of what is considered as apparent preconsolidation pressure in constant stress heating tests.

TO THE QUESTION OF DETERMINING THE VALUES OF ADHESION AND ANGLE OF INTERNAL FRICTION OF ROCK FORMATIONS

Mine Surveying and Subsurface Use
The paper analyses the strength parameters of rocks tested under uniaxial and volumetric stress states. Based on their results, the Mohr stress limit circles and their envelope line were plotted in the field of tangential and normal stresses. According to its slope and intersection with the tangent stress axis, the cohesion (C) and the angle of ...

Influence of Anisotropic Internal Friction Angle on the Stability of Uniform Soil Slopes

Applied Mechanics and Materials, 2012
The effect of anisotropy of friction angle in natural deposited soil on the stability of soil slopes was studied in this paper. Stability analysis was performed on a uniform soil slope with anisotropic friction angle. Spencer’s method was used, and the variation of friction angle was assumed to be linear to the change of direction of the slip surface ...
