Inelastic Behavior of Random Arrays of Identical Spheresrom a consideration of force and moment equilibrium of the individual grains and simple but appropriate assumptions regarding the force of contact between grains and the statistical geometry of their packing.

Fractal Fragmentation and Frictional Stability in Granular Materialsuge have found a fractal (power-law) distribution with a fractal dimension of 1.6±0.1 in 2D planar section (or 2.6±0.1 for the isotropic distribution in 3D). A simple fragmentation mechanism which leads to a fractal distribution with this dimension can be formulated. It assumes that a particle’s fra

Mechanical Behaviour of Mixtures of Kaolin and Coarse Sandmm) affects the mechanical properties of a clay (kaolin). The behaviour of the mixtures can be understood through the use of appropriate volumetric variables. At one extreme, if the coarse particles do not interact then the response of the mixture may be dependent on volumetric packing of the clay m

A Characteristic State Plasticity Model for Granular Materialsween shear stresses and mean stress plays a dominant role. Within the framework of plasticity theory this leads to a family of self-similar yield surfaces. Classical critical state theory was developed in terms of a two-dimensional stress space with mean stress . and maximum shear stress 1/2.. The u

On the Constitutive Potential for Powder and Porous Bodiese cylindrical unit cell model is used to evaluate the rate-dependence of the constitutive law for isotropic porous bodies. The special choice of the stress-strain rate relation for the matrix material has provided the exact analytical expression for the given law which has been obtained for a wide s
