Summary

An investigation is made of the void growth in a two-phase material subjected to high strain-rate deformation which is obtained by Split Hopkinson bar apparatus under uniaxial tension mode.The target two-phase material is polycrystalline Al-Si alloy.The stress-strain curves of Al-Si at various strain rate \(\mathop \varepsilon \limits^{\cdot}=500 \sim 1500/{\rm{sec}}\) indicate that this two-phase material exhibits high strain-rate sensitivity. It was found by SEM study that void density f increases with \(\mathop \varepsilon \limits^{\cdot}\). Then, the void growth model of Taya et al. is used to predict the void density fat the fracture surface and in the parallel region, resulting in a reasonably good agreement with the experimental results.
