Publisher Summary An important failure mechanism in ductile metals and their alloys is by
growth and coalescence of microscopic voids. In structural materials, the voids nucleate at …

A general method called FE2 has been introduced which consists in describing the behavior
of heterogeneous structures using a multiscale finite element model. Instead of trying to …

In mechanical engineering and structural analysis there is a significant gap between the
material models currently used by engineers for industry applications and those already …

Strain gradient plasticity has been the subject of extensive research in the past 40 years in
order to model size effects in metal plasticity, on the one hand, and provide finite width shear …

Deformation and fracture are investigated at room temperature in steel through tension and
compression tests. Round smooth bars and cylinders are used to characterize the …

The aim of this paper is to incorporate plastic anisotropy into constitutive equations of porous
ductile metals. It is shown that plastic anisotropy of the matrix surrounding the voids in a …

A phenomenological yield function is proposed to represent the plastic anisotropy of
aluminum sheets. It is an extension of the functions given by Barlat et al.[Int. J. Plasticity 7 …

Significant progress has been recently made in modelling the onset of void coalescence by
internal necking in ductile materials. The aim of this paper is to develop a micro-mechanical …

The present study investigated the hydrogen-related fracture behavior of specimens with
different stress concentration factors through microstructure observation, finite element (FE) …

Computational contact mechanics is a broad topic which brings together algorithmic,
geometrical, optimization and numerical aspects for a robust, fast and accurate treatment of …
