In-situ SEM experiments revealed that microstructural strain paths can differ significantly from macroscopically imposed 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 here experiments using a custom-designed bulge test setup, and supporting crystal plasticity simulations, which enable us to discuss the influence of multiaxial loading conditions on the microstructural strain path development and, in turn, in the ductile damage process.
