Aluminium 5083 alloy reinforced with B4c/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 AA5083 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
consider for the these composites to analysie the axial,hoop and hydro satatic stress for all the cases of metal matrix composites.
AA5083+9MMC composite very close to the effective strain line compare 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 compare to 6MMC and base alloy
it indicates that they are exhibit the good plastic properties.
