A bonded-particle model for rock
D.O. Potyondy,Peter Cundall +1 more
TL;DR: In this paper, a numerical model for rock is proposed in which the rock is represented by a dense packing of non-uniform-sized circular or spherical particles that are bonded together at their contact points and whose mechanical behavior is simulated by the distinct element method using the two-and three-dimensional discontinuum programs PFC2D and PFC3D.

Effects of strain rate on the mechanical and fracturing behaviors of rock-like specimens containing two unparallel fissures under uniaxial compression
TL;DR: In this paper, the effects of strain rate on the mechanical and fracturing behaviors of rock-like specimens containing two unparallel fissures with varying inclination angles (α2) were investigated, and it was shown that α2 and strain rate significantly affect the strength and deformation characteristics and the failure modes of fissured specimens.

Applications of Discrete Element Method in the Research of Agricultural Machinery: A Review
TL;DR: This paper reviewed the application research status of DEM in two aspects: first is the DEM model establishment of common agricultural materials such as soil, crop seed, and straw, etc, and the simulation of typical operational processes of agricultural machines or their components.

A discrete numerical model for granular assemblies
Peter Cundall,Otto D. L. Strack +1 more
TL;DR: The distinct element method as mentioned in this paper is a numerical model capable of describing the mechanical behavior of assemblies of discs and spheres and is based on the use of an explicit numerical scheme in which the interaction of the particles is monitored contact by contact and the motion of the objects modelled particle by particle.

The Phenomena of Rupture and Flow in Solids
TL;DR: In this article, the authors investigated the effect of surface scratches on the mechanical strength of solids, and some general conclusions were reached which appear to have a direct bearing on the problem of rupture, from an engineering standpoint, and also on the larger question of the nature of intermolecular cohesion.
Verification, Validation, and Confirmation of Numerical Models in the Earth Sciences
TL;DR: Verification and validation of numerical models of natural systems is impossible because natural systems are never closed and because model results are always nonunique.

Zdeněk P. Bažant,Jaime Planas +1 more
- 29 Dec 1997
TL;DR: In this paper, the authors used the Weibull-type approach to measure the effect of size effect on structural strength of a crack and its size effect in terms of the number of cracks and the size of the cracks.
