Ductile failure in polycrystalline aluminum alloys is explored through uniaxial tension and
notched tension experiments. Specimens obtained through tests interrupted at various
stages of deformation and failure evolution are examined through microscopy to discern the
mechanisms of failure and to evaluate the local strain evolution quantitatively. Fractographic
observations are used to identify the onset and evolution of damage processes during
deformation and failure of these aluminum alloys. Local strain levels are estimated from …

Ductile failure in polycrystalline aluminum alloys under pure shear as well as with
superposed tension and compression loading is explored through the modified Arcan shear
experiments. Specimens obtained through tests interrupted at various stages of deformation
and failure evolution are examined through quantitative microscopy to discern the
mechanisms of failure and to evaluate the local strain evolution quantitatively. Fractographic
observations are used to identify the onset and evolution of damage processes during …
