- Abstract
- In this study, a serial sectioning process was used to visualize and model the mechanical and thermal behavior of SiC particle reinforced aluminum composite. 2 dimensional microstructure images were acquired and reconstructed to develop 3 dimensional geometries for finite-element modeling (FEM). The experiments of compression and thermal expansion coefficient were performed for comparison of FEM and experimental results. To confirm that this approach is a significant improvement over 3D unit cell modeling, it was also simulated and compared to serial sectioning process. The young’s modulus of the composite predicted by the 3D microstructure model correlated very well with experimental. But plastic region and thermal expansion coefficient are different from experimental results because interface condition between a matrix and particles was ignored.
