Indentation analysis of mechanical behaviour of torsion-processed single-crystal copper by crystal plasticity finite-element method modelling

Journal Article


Abstract


  • A crystal plasticity finite-element (CPFE) constitutive model is developed to investigate the mechanical properties and microtexture evolution of torsion-processed single-crystal copper by indentation modelling. The mesh-to-mesh solution (mapping) is used during modelling to bridge the gap between two different processes (torsion and indentation) and integrate them. The parameters for CPFE modelling are validated by comparison with experimental observations. The numerical results indicate that linearly increased effective strain along the radius of the torsion-processed single-crystal copper workpiece may slightly improve its radical hardness and ductility, while grain refinement will enhance its radical hardness and ductility significantly.
