Large deformation

This paper uses the discrete element method to simulate a soft grain that can deformed without rupturing. This soft grain is composed of rigid primary particles with a cohesive contact law between them. The results showed that rigid primary particles within the deformable grain can move and rearrange in response to vertical compression.

For this study, different volume fraction (vol.%) of particulate alumina (Al2O3) reinforced aluminium alloy (Al 6061) with 5 vol.%, 15 vol.% and 25 vol.% are produced by powder metallurgy method. These samples were subjected to biaxial stresses in order to investigate the behaviour of the metal matrix composites (MMCs). Microstructure analysis on the individual sample before and after loading was performed under scanning electron microscopy. The small particles of 2 µm in size have exhibited strong interfacial bonding with the matrix.
