Experimental and Finite Element Analysis of Compression Behaviour of Sic/Fa/Grparticulatesfilled Aa 7075 Alloy Composites

Aluminium 7075 alloy, reinforced with SiC/FA/Gr metal matrix composite was fabricated at different weight ratios 6,9 and 12 mmcs using stircasting method under vertex route. The objective of this work is to determine the non-linear plastic properties of AA7075 and their composites using a powerful finite element analysis software ANSYS. The ANSYS results are compared with analtical calculations and they are very close to each other. Two different aspect ratios (H/D 1.0 and H/D1.5) are considered for these composites to analysie the axial,hoop and hydro satatic stress for all the cases of metal matrix composites.AA7075+9MMCcomposite very close to the effective strain line compared to other composites and base alloy it indicates; the good ductile properties are presented. H/D ratio 1.5 the hoop stress is increased for 9 and 12 MMC compared to 6MMC and base alloy, it indicates that they exhibit the good plastic properties.
