Polymer chain scission at constant tension - an example of force-induced collective behaviour

, 2011
The breakage of a polymer chain of segments, coupled by anharmonic bonds with applied constant external tensile force is studied by means of Molecular Dynamics simulation.

Evolution of particle breakage studied using x-ray tomography and the discrete element method

EPJ Web of Conferences, 2017
Particle breakage can significantly change the fabric (size and shape of particles and contact network) of a granular material, affecting highly the material's macroscopic response.

Aging in Structural Changes of Amorphous Solids: A Study of First Passage Time and Persistence Time Distribution

, 2015
The time distribution of relaxation events in an aging system is investigated via molecular dynamics simulations. The focus is on the distribution functions of the first passage time, $p_1(\Delta t)$, and the persistence time, $p(\tau)$.

Breakage of Anisotropic Rod-Shaped Particles.

, 2016
In this experimental study, behaviour of dry granular layers of monodisperse cylindrical particles (8x1 mm) under uniaxial compression was studied. The layer compressibility and PSD were evaluated. The effect of several parameters was investigated: piston speed, layer size (diameter and height), applied pressure.

Macro-micro scale investigation of gradation area effects on particle breakage characteristics of coarse-grained soils

Frontiers in Materials
Particle breakage is a significant cause of deformation and strength degradation in coarse-grained soils. Under the influence of gradation, the characteristics of particle breakage become more complex, posing challenges to the safe design of coarse ...

Tensile Breakage of Particles in Granular Media

IOP Conference Series: Earth and Environmental Science
Abstract This paper proposes a method to assess the probability of breakage by tension of particles in a granular medium subjected to a triaxial stress state. It is considered that the resistant tensile stress and the intragranular acting one are random variables.

Saltation on Mars and expected lifetime of Viking 75 wind sensors [PDF]

With the use of the wind-tunnel measurements of Bagnold and Zingg, a model is developed for estimating the parameters that describe the flux of sand on Mars. Application of this model to the sensor-breakage problem indicates that the expected lifetime on

Simulation of the effect of bond strength on the breakage pattern of agglomerates by Distinct Element Method [PDF]

Chemical, pharmaceutical and food industries amongst many others use agglomerates either as intermediate or manufactured products. The mechanical strength of agglomerates under impact or shear deformation during handling and processing is of great ...
