摘要: A planar array of hexagonal grains was used as a two-dimensional model the ideal multicrystal, and anisotropic finite element method employed to analyse features about stress elastic strain energy distributions. The purpose investigate effects grain boundary triple junction on local mechanical properties multicrystal. results show that distributions stresses are distinctly inhomogeneous in macroscopic isotropic multicrystal under uniaxial load. highest lowest energies exist at some boundaries junctions. resolved shear each primary slip system occurs boundaries, but not Slip may first initiate from stiffer grain.
