Modelling of fracture in metal powder compaction process

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

This paper presents analysis on the prediction of crack initiation and propagation during the cold compaction process of metal powder. Based on the fracture criterion of granular material in compression, a displacement based finite element model with adaptive remeshing technique has been developed to analyse crack growth in iron powder compact. Friction between crack faces is modelled using the six nodes isoparametric interface elements, incorporating a constitutive model of friction based on plasticity. Simulations of the predicted crack growth are presented and discussed in terms of the effects of shear stress and relative density distributions as the compaction proceeds.
