The past 20 years have seen substantial work on the modeling of ductile damage and
fracture. Several factors explain this interest.(i) There is a growing demand to provide tools …

Theoretical concepts of sintering were originally based upon ideas of the discrete nature of
particulate media. However, the actual sintering kinetics of particulate bodies are …

The influence of each of the six different types of morphological imperfection—waviness,
non-uniform cell wall thickness, cell-size variations, fractured cell walls, cell-wall …

In this paper, we present a modified density-dependent Drucker-Prager Cap (DPC) model to
simulate the compaction behaviour of pharmaceutical powders. In particular, a nonlinear …

Constitutive models are developed for stage I cold compaction of powders under general
loading. Densification is assumed to occur by plastic deformation at the isolated contacts …

Aluminum foams are currently being considered for use in lightweight structural sandwich
panels and in energy absorption devices. In both applications, they may be subject to …

Powder die compaction is modelled using the finite element method and a
phenomenological material model. The Drucker–Prager cap model is modified with the goal …

The formation of cup-cone fracture in round bars and of slant fracture in plane strain
specimens is studied using the finite element (FE) method. Constitutive models proposed by …

Natural and induced stress states around man-made openings in rock generally have
different magnitudes along the principal axes. Accordingly, appropriate stability analyses …

This article provides an overview of research efforts with an emphasis on the fabrication of
metal matrix nanocomposites (MMNCs) reinforced by graphene nanoplatelets (GNPs) …
