WebThe volume change behavior and interparticle friction depend on the density of the particles, the intergranular contact forces, and to a somewhat lesser extent, other factors such as the rate of shearing and the direction of the shear stress. The average normal intergranular contact force per unit area is called the effective stress. WebMar 4, 2024 · Particle surface roughness plays a pivotal role in dictating the rheological behavior of dense suspensions of rigid particles as it promotes interparticle contacts, leading to friction and contact ...

James currently leads cross-disciplinary collaborative efforts to develop … Web4.0 Conclusion The role of interparticle friction on the micromechanical strength characteristics in granular media was analyzed. From the analysis results, the following conclusions were arrived at: i. Interparticle friction has a dual contribution to the normal stress contribution of strong contact forces to principal stresses.
WebOct 8, 2002 · Using this value for μ p and accounting for interparticle friction on both sets of contact surfaces in 2-D (e.g., surfaces parallel to the shear plane and surfaces perpendicular to the shear direction upon which rolling or sliding must occur to accommodate shear in an extended 2-D assembly) yields an expected average friction …
