Abstract Scope |
A novel modeling capability has been developed which permits consideration of metallic microstructure evolution in thermomechanical forming analyses. The evolution of microstructural features such as crystallographic texture and grain constitutive response are predicted using a crystal plasticity model. This is coupled with the state of the art remeshing/adaptivity capabilities in commercial finite element software LS-DYNA. By allowing remeshing and properly remapping the microstructural features to the new mesh, the modeling framework is able to simulate significantly larger deformation (up to 1000% strain) than traditional crystal plasticity finite element. Thus, the developed model permits large deformation forming operations to be simulated, predicting the final microstructure as well as shear band localization and appearance of localized damage. The model has been calibrated and successfully applied to the high temperature forging of Al-Li 2070 into complex geometries including an airfoil. The model allows its application to a wide range of processes and materials. |
