Abstract Scope |
To develop predictive model for monotonic and cyclic loading of polycrystalline metallic alloys, there is a need for quantitative experimental assessment of plastic deformation at the scale of the microstructure over 3D representative field of view. Moreover frameworks for direct comparison of experimental measurements and numerical simulation results need to be established. New developments in High-Resolution Digital Image Correlation (HR-DIC) and 3D tomography provide unique opportunities to capture large datasets that detail elastic and plastic deformation in relation to 3D microstructure. Examples are given during cyclic and monotonic deformation of 718 nickel-based superalloys for direct comparison with 3D numerical simulations. The effects of 3D grain and precipitate structures on plastic localization are detailed and their impact on nickel based-superalloy fatigue modeling is explained. |
