The paper discusses the basic issues of the local approach to ductile fracture of structural
metals, with particular emphasis on the failure due to microvoid development. The …

A strain gradient void-driven ductile fracture model of single crystals is proposed and
applied to simulate crack propagation in single and oligo-crystal specimens. The model is …

Voids can be observed at various scales in ductile materials, frequently of sizes lower than
the grain size, leading to porous single crystals materials. Two local deformation modes of …

This work investigates internal damage by void growth in NT microstructures via crystal
plasticity. The framework incorporates length-scale effects and explicitly models twin …

Void coalescence is known to be the last microscopic event of ductile fracture in metal alloys
and corresponds to the localization of plastic flow in between voids. Limit-analysis has been …

Size effects have been predicted at the micro-or nano-scale for porous ductile materials from
Molecular Dynamics, Discrete Dislocation Dynamics and Continuum Mechanics numerical …

A model of coalescence by internal necking of primary voids is developed which accounts
for the presence of a second population of cavities. The derivation is based on a limit …

Ductile fracture generally relates to microscopic voiding and to strain localization in metallic
materials. When the void size is reduced to the nanoscale, size effects often lead to a …

This paper presents the results of experimental research about the influence of temperature
and strain rate on microstructure and fracture mechanism of C25 mild commercial steel. This …

Nanoporous materials have attracted extremely intense scientific attention since the
photoluminescence discovery at room temperature because of the quantum confinement …
