A crystal plasticity based full-field microstructure simulation approach is used to virtually determine mechanical properties of sheet metals. Microstructural features like the specific grain morphology and the crystallographic texture are taken into account to predict the plastic anisotropy. A special focus is on the determination of the Lankford coefficients and on the yield surface under pla...

Modelization of the elastoplastic behavior of metallic polycrystals based on micro-macro transitions using the powerful self-consistent scheme was developed for a local constitutive equation at the single crystal level. Numerical results concerning yield surface, subsequent yield surface, induced texture and plastic as well as elastic anisotropy, second order residual stresses and stored energy...

Abstract The pure cross-anisotropy is understood as a special scaling of strain (or stress). scaled tensor used an argument in the elastic stiffness compliance). Such anisotropy can be overlaid on top any stiffness, particular one obtained from potential with its own stress-induced anisotropy. This superposition does not violate Second Law. method also applied to other functions like plastic po...

BACKGROUND AND PURPOSE Hemispherectomy is a neurosurgical procedure to treat children with intractable seizures. Postsurgical improvement of cognitive and behavioral functions is observed in children after hemispherectomy suggesting plastic reorganization of the brain. Our aim was to characterize changes in DTI scalars in WM tracts of the remaining hemisphere in children after hemispherectomy, ...

The work material in metal working operations always shows some kind of anisotropy. In order to simplify the theoretical analysis, especially considering bulk deformation processes, anisotropy is usually neglected and the material is assumed to be isotropic. On the other hand, the analysis that considered the influence of anisotropy seldom incorporates the influence of friction. For predicting ...
