Understanding the deformation processes leading to the failure of polycrystalline structural materials is one of the key challenges in materials science. Significant progress has been achieved over the past decades, thanks to both cutting-edge experimental characterization techniques and computational methods. Still, the localization of plasticity in slip bands and the propagation of plasticity through a polycrystalline aggregate are not fully understood. The French ANR research project 3DiPolyPlast aims at improving our understanding of the multi-scale processes involved in plastic deformation by combining experimental observations with concomitant numerical simulation of strain localization. 3DiPolyPlast unites four leading research institutes covering the fields of X-ray characterization, electron microscopy and crystal plasticity modelling, respectively.
