On modeling the development of crystallographic texture in bulk forming processes

摘要: Abstract A mathematical formulation is presented for modeling the evolution of deformation induced crystallographic texture in steady state bulk forming processes. The treats material response polycrystalline aggregate as a statistical function individual grains. viscoplastic relationship assumed along grain slip systems. Strain hardening on these systems included. stiffness matrix code presented. streamline technique has been used to integrate equation this derived and its implementation large Eulerian finite element lattice rotation system hardness. As an application, multipass aluminum rolling simulation modeled. numerical predictions have compared with reported experimental textures.
