MICROSTRUCTURAL MODELING OF FAILURE IN POLYCRYSTALLINE MATERIALS

摘要：

Dislocation-density basedmultiple-slip constitutive formulations and specialized computational schemes are introduced to account for grain-boundary (GB) effects in polycrystalline aggregates.New kinematically based interracial grain-boundary regions and formulations are introduced to account for dislocation-density transmission,absorption,and pile-ups that may occur due to random andCSL grain-boundary misorientations and their effects on crack and void growth.
