Abstract We present a model of solids made from polygonal cells connected via beams. We calculate the macroscopic elastic moduli from the beam and cell parameters. This modellisation is particularly suited for the simulation of fragmentation processes. We study the effects of an explosion inside a circular disk and the impact of a projectile and obtain the fragment size distribution. We find that if breaking only happens under tensile forces a layer on the free wall opposed to impact is first… 
Mechanisms in impact fragmentation
The brittle fragmentation of spheres is studied numerically by a 3D Discrete Element Model. Large scale computer simulations are performed with models that consist of agglomerates of many spherical
Two-dimensional dynamic simulation of fracture and fragmentation of solids
We present a two-dimensional discrete model of solids that allows us to follow the behavior of the solid body and of the fragments well beyond the formation of simple cracks. The model, consisting of
On the application of a discrete model to the fracture process of cohesive granular materials
We present a two-dimensional model of heterogeneous cohesive frictional solids where the material structure is idealized by a discrete granular particle assembly. Our discrete model is composed of
Fragmentation processes in impact of spheres.
The results significantly improve the understanding of the fragmentation process for impact fracture since besides reproducing the experimental observations of fragment shapes, impact energy dependence, and mass distribution, the authors also have full access to the failure conditions and evolution.
From solids to granulates - Discrete element simulations of fracture and fragmentation processes in geomaterials
We present a two-dimensional model of heterogeneous cohesive frictional solids where the material structure is idealized by a discrete granular particle assembly. Our discrete model is composed of
Effect of Confining Pressure on Particle Breakage of Assemblies of Simulated Angular particles Using Discrete Element Method
A model is presented to simulate the breakage of two-dimensional polygon-shaped particles with using DEM (Discrete Element Method). In this model, initial shapes of the particles can be defined and
A direct fragmentation method with Weibull function distribution of sizes based on finite- and discrete element simulations
Abstract A direct method is proposed to rapidly fragment bodies during impulse-based discrete element method simulations of multiple body interactions. The approach makes use of patterns and size
Discrete-element model for dynamic fracture of a single particle
Abstract We investigate the dynamic fracture of a single particle impacting a flat surface using 3D DEM simulations based on a fragmentation model involving both a stress threshold and a fracture
Calculation of the incremental stress-strain relation of a polygonal packing.
The constitutive relation of the quasistatic deformation on two-dimensional packed samples of polygons is calculated using molecular dynamics simulations and shows that the stiffness tensor can be directly related to the microcontact rearrangements.
Three-dimensional bonded-cell model for grain fragmentation
We present a three-dimensional numerical method for the simulation of particle crushing in 3D. This model is capable of producing irregular angular fragments upon particle fragmentation while


A novel simulation method for the quasi‐static mechanics of granular assemblages
The following is a description of a new computer‐simulation technique for the quasi‐static particle mechanics of granular media and its application to the dilatant simple shear of periodic 2D arrays
Self-organized criticality in fragmenting.
The measured mass distributions of fragments from 26 fractured objects of gypsum, soap, stearic paraffin, and potato show evidence of obeying scaling laws; this suggests the possibility of
Experimental study on the velocity of fragments in collisional breakup
Abstract The motion of fragments following a catastrophic destruction by either a normal or an oblique impact at 2.5–2.9 km sec−1 into cubic and spherical basalt targets was studied with a high-speed

An automaton for fractal patterns of fragmentation
FRACTURES in the Earth's crust have a fractal structure over a wide range of length scales. A micromechanical model has been proposed1 for the formation of fractal patterns of fragmentation in fault

Fragmentation of Long Thin Glass Rods
Fragment-size and -mass distributions of long, thin glass rods (1500 mm long and 2 mm diameter) are studied experimentally by dropping horizontal glass rods. At lower falling height (about 1 m drop),
Laboratory simulation of planetesimal collision
Low-velocity impact experiment on rocks was performed to reveal a nature of collision process of planetesimals. Projectiles of mild steel (S15CK) and rocks (tuff and basalt) with velocities of 17 to
Fractals and fragmentation
If the number-size distribution of objects satisfies the condition N ∼ r−D, then a fractal is defined with a fractal dimension D. In many cases, fragmentation results in a fractal distribution. This
however (for it was the literal soul of the life of the Redeemer, John xv. io), is the peculiar token of fellowship with the Redeemer. That love to God (what is meant here is not God’s love to men)
