Small specimen test techniques (SSTTs), developed for scarce materials, industrial
products, in-service equipment, etc., could be challenging to obtain sufficient materials for …

It has been accepted that the formability of a sheet metal with a moderate ductility can be
limited by not only localized necking (LN), but also ductile fracture (DF). In this study, a …

Friction stir spot welding (FSSW) is a solid-state welding process, wherein the properties of a
weld joint are influenced by the state of friction and localised thermodynamic conditions at …

This paper deals with the comparative investigation of fracture envelopes constructed by the
3D-DIC and hybrid inverse analyses. For the evaluation of fracture limits of the DP980 1.2 t …

Numerical approaches for fracture modeling have been proposed for various metallic
materials, including high-strength steels and aluminum alloys. However, the quantitative …

An accurate failure criterion is crucial for mechanical and structural design. In this paper, the
effects of three stress invariants on material failure are studied based on microscopic …

Ductile fracture occurs with large plastic deformation prior to fracture and is primarily
characterized by voids of varying sizes. In this work, a new approach based on machine …

The mechanical properties of thermally stable ultrafine-grained Al metal matrix composites
dispersion strengthened and stabilized by nano-metric in-situ Al 2 O 3 (named HITEMAL©) …

Although ductile fracture properties of aluminum alloy have been examined by several
research works, the effect of strain rate in small punch test is still unclear. An investigation on …

Ductile fracture of metal often occurs in the plastic forming process of parts. The
establishment of ductile fracture criterion can effectively guide the selection of process …
