Beyond the peak load, the bearing capacity of a … Web2 days ago · In other words, in the DSA region, increasing in applied strain rates results in lower flow stress which in turn this prompts the occurrence of strain localization during deformation [4]. A very first investigation by Cottrell [5] showed that solute atoms in aluminum usually diffuse too slowly to cause appreciable strain ageing at room …
WebMar 20, 2024 · In eclogite with a 50% garnet fraction, deformation starts to localize at a strain of about 2.5%, with omphacite grain boundaries being the loci of strain localization (Figure 11a, center). The onset of localization coincides with yielding; further localized zones evolve into a conjugated network (Figures 11a and 11b center) and form until peak ...

WebEqual-Channel Angular Pressing (ECAP) is a method used to introduce severe plastic deformation into a metallic billet without changing its geometry. In special cases, strain localization occurs and a pattern consisting of regions with high and low deformation (so-called shear and matrix bands) can emerge. This paper studies this phenomenon …
WebApr 7, 2024 · To better understand the correlation between microstructure and deformation behavior during shear, a localization of stresses at predicted sites is necessary.
