Experimental detection of forming limit strains on samples with multiple local necks

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1260922

Sheet metal formability is traditionally described by the forming limit curve (FLC). Experimental FLCs are obtained by performing formability tests and determining failure strains. The strains are usually measured either by etching a grid on the sheet surface or by digital image correlation (DIC). D...

Determination of Ductile Fracture Parameters of a Dual-Phase Steel by Optical Measurements

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1046845

Marciniak–Kuczynski and Nakajima tests of the dual-phase steel Docol 600DL (www.ssab.com/) have been carried out for a range of stress-states spanning from uniaxial tension to equi-biaxial tension. The deformation histories of the specimens have been recorded by digital images, and the displacement ...

Evolution of mechanical properties in a 7075 Al-alloy subject to natural ageing

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1039439

A series of mechanical tests was used to characterise the evolution of yield strengths, r-values and work hardening during the natural ageing of a commercial 7075 aluminium alloy. The results show that there is a significant underlying change in anisotropy between the original O-condition and soluti...

Simulation of yield surfaces for aluminium sheets with rolling and recrystallization textures

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+976368

The influence of crystallographic texture and homogenization scheme on the yield surface for aluminium sheets has been studied numerically. A rate-dependent single crystal plasticity model was adopted to describe the behaviour of the grains, whereas the behaviour of the polycrystal was obtained eith...
