The influence of underlying microstructure on surface stress and strain fields calculated by crystal plasticity finite element method

The objective of this work is to assess the accuracy of different approaches to represent the microstructure of a polycrystalline sample using EBSD (electron backscatter diffraction) maps of a single external surface as input. To this aim, the stress and strain fields predicted using the finite element method and considering either columnar grains, extruded from the surface, or synthetic, obtained by random misorientation through the thickness...
