Experimental Investigation of True Stress and True Strain on Copper Based Metal Matrix Composite during Compression Test using Design of Experiments

Objective: In this Paper, the effect of reinforcement content, load and time was analysed on the true stress and true strain during compression testing of (Copper/Silicon Carbide) Cu/SiC composite using design of experiment. Methods:Statistical analysis is performed to identify the significant factor which affects the mechanical behaviour of the composite.Three types of composite samples were made-up using different SiC content by stir casting process. The true stress and true strain of composites were evaluated for a defined variety of load and time. Findings: With the increase of SiC content, load, and time the true stress of a composite improved. With the increase of SiC content, true strain decreased while with increase of load and time, true strain increased. Vickers hardness test is also performed on developed samples. It is found that percentage increase in the reinforcement content of MMC increases the hardness of the composite. Applications/Improvements: More analysis and evaluation on copper composite can be performed by varying various parameters like increasing reinforcement percentage and tests can be conducted at elevated temperatures.
