The current medical implants are being developed using materials like Co-Cr, stainless
steel, and titanium alloys. These conventional implant materials induce a stress shield effect …

Cold-isostatic pressing (CIP) is a powder-based, near-net-shape technology for the
production of metal and ceramic components. CIP has been commonly used for processing …

This paper presents simulations of cold isostatic and closed die compaction of powders
based on the Discrete Element Method. Due to the particulate nature of powders …

Analysis of mechanical contact of solids is of interest not only regarding a variety of
mechanical assemblies but also on a smaller scale such as roughness properties of …

A multi-particle finite element model (MPFEM) was used to explore the densification yield
surfaces of a collection of monosize particles in 2-D. Individual particles discretized with a …

A model for the densification of spherical powders is developed for the early stages of cold
and hot compaction under general loading. General viscoplastic properties are adopted …

A one-dimensional, numerical model of time-evolving firn densification was used to simulate
the response of the density profile through an ice sheet to changes in the temperature …

Aims. Radiometric ages for chondritic meteorites and their components provide information
on the accretion timescale of chondrite parent bodies, and on cooling paths within certain …

A numerical procedure, based on a discrete element method (DEM), for analysing cold
compaction of spherical powders, is presented. In the numerical model, packing followed by …

Context. The cooling histories of individual meteorites can be empirically reconstructed by
using ages obtained from different radioisotopic chronometers having distinct closure …
