Grain Boundary Effects and Failure Evolution in Polycrystalline Materials

Ashmawi, W. M. / Zikry, M. A.

Abstract Dislocation density based multiple-slip constitutive formulations and specialized computational schemes are introduced to account for large-strain ductile deformation modes in polycrystalline aggregates. Furthermore, new kinematically based interfacial grain boundary regions and formulations are introduced to account for dislocation density transmission, absorption, and pile-ups that may occur due to grain boundary misorientations and properties.
