[SY-C12] Deformation Behaviour for Two-Phase Composites under Large Deformations using Micromechanical Analysis
This study presents a micromechanics approach for the elasto-viscoplastic behaviour of eutectic materials and structures. In this approach, the high-fidelity generalised method of cells (HFGMC) is applied for the prediction of the effective behaviour of two cold-drawn Cu-Ag composites with different drawing strains and to obtain the field (deformation gradient and stress) distributions in the composite. Both phases (Cu or Ag) are rate-dependent crystal plasticity material constituents. HFGMC is applied for analysing the deformation behaviour of two-phase Cu-Ag composites under uniaxial compression. The micromechanical analysis has been verified by comparison with experimental and finite element simulation results. Results in terms of deformation behaviour and field distributions are given for two different cold-drawn composites.
