Studies of texture gradients in the localized necking band of AA5754 by EBSD and microstructure-based finite element modeling

This work aims to understand the texture distribution in the localized necking band formed during uni-axial tension of AA5754 using an edgeconstrained, plane strain post-necking FE model. The model domain is a long cross section of the band. Initial grain structure is mapped into the mesh from EBSD data using a modified Voroni-cell interpolation and considering pre-straining prior to localized necking. The material points in grains are assumed …
