| Abstract Scope |
In-situ SEM deformation experiments utilizing digital image correlation demonstrate that microstructural strain localization events exhibit a variety of micro-level strain paths. For example, micro-level local strain paths ranging from uniaxial tension to plane-strain tension can be seen in a single material when the macroscopically imposed strain path is the former. Our previous work revealed the importance of local martensitic configurations on this behavior in dual-phase (DP) steels deformed in uniaxial tension. For a better understanding of the damage behavior in this material, this phenomenon should be investigated under multiaxial loading conditions as well. To fill this gap, we present experiments using a custom-designed bulge test setup to comment on the influence of multiaxial loading conditions on the microstructural strain path development and to discuss the distribution of microscopic strain localizations. Ultimately, this study leads to an enhanced understanding of the orientation and the distribution of microscopic strain localizations in metals. |
