An approach to evaluate internal friction angle from dynamic penetration tests
2009This paper presents an approach to predict the internal friction angle of cohesionless soils from dynamic penetration tests. The proposed methodology allies the dimensional equation technique (TT numbers) with a numerical simulation routine that is able to reproduce the dynamic test response for a SPT or for any other dynamically driven device such as ...

Experimental Research on Cohesion and Internal Friction Angle of the Double‐base Propellant
Propellants, Explosives, Pyrotechnics, 2013AbstractA 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 ...

Implications of thermal sensitivity of the static internal friction angle
2009Thermal 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.

Influence of Anisotropic Internal Friction Angle on the Stability of Uniform Soil Slopes
Applied Mechanics and Materials, 2012The 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 ...

Estimation of internal friction angle for working platform materials by plate load test
Proceedings of the Institution of Civil Engineers - Geotechnical EngineeringThis paper reviews the load–settlement behaviour of 499 plate load tests of various diameters undertaken on granular soils and working platform materials to determine the angle of internal friction mobilised by the test. The observed settlement of individual plate load tests at relatively small settlement has been extrapolated to a theoretical failure

PhiFlex: A Flexible Strategy for Estimating the Internal Friction Angle from SPT Test
This work proposes and analyzes a flexible model, named PhiFlex, for estimating the internal friction angle (φ) in granular soils based on the N60 value from Standard Penetration Tests (SPT). The model integrates and harmonizes various historical empirical formulas through a continuous interpolation between two branches (nonlinear and logarithmic ...openaire +1 more source
