Abstract:

The finite-element-based microstructural modeling technique developed by Suh et al. Suh, Y. S. Joshi, S. P. Ramesh, K. T. Acta. Mater. 2009, 57, 5848 was reviewed and used for studying the different responses between isotropic and anisotropic aluminum matrix with varying particle sizes. The results show that the overall response of the material was identical when the matrix material was changed from isotropic-elasticplastic aluminum to anisotropic-elasticisotropic-plastic aluminum, especially for the 5 volume fraction. However, the anisotropic-elasticisotropic-plastic aluminum exhibited a lower elastic modulus than that of the isotropic-elasticplastic-aluminum. Also, the flow stresses were lower for anisotropic-elasticisotropicplastic aluminum for the 20 volume fraction.
