Study of particle rearrangement during powder compaction by the Discrete Element Method
TL;DR: In this paper, the authors present simulations of cold isostatic and closed die compaction of powders based on the Discrete Element Method (DE) and show that local rearrangement has some effect on average quantities such as the average coordination number, the average contact area and the macroscopic stress.
Journal ArticleDOI
Relation between percolation and particle coordination in binary powder mixtures
Didier Bouvard,F.F. Lange +1 more
TL;DR: In this article, the critical volume fraction of inclusions required to form the first percolative cluster strongly depends on the inclusion to matrix particle size ratio and the fraction of the inclusions belonging to a connective cluster is a size-ratio-insensitive function of the inclusion-inclusion coordination number.
Journal ArticleDOI
Discrete element modeling of metallic powder sintering
TL;DR: In this paper, the free sintering of metallic powders is investigated by the discrete element method which allows the particulate nature of the material to be explicitly taken into account, and its use allows a favorable comparison of simulated densification rates with experimental data from the literature.
Journal ArticleDOI
Deformation of Interparticle Necks by Diffusion-Controlled Creep
TL;DR: In this paper, the deformation of a neck between two spherical particles of the same size by coupled grain-boundary and surface diffusion has been simulated numerically through the finite-difference method.
Journal ArticleDOI
Modeling the effective thermal conductivity of random packing of spheres through densification
C. Argento,Didier Bouvard +1 more
TL;DR: In this paper, the thermal conductivity of densified random packing of spheres is studied and a continuous analytical expression is proposed to describe the relation between the effective thermal conductivities and the relative density of the packing.
