Optimization of Process Parameters of Fracture Toughness Using Simulation Technique Considering Aluminum-Graphite Composites

The main objective of this work is to optimize the process parameters of fracture toughness such as composition of the material, a/W ratio and testing methods using the simulation technique using ANSYS tool. The material used here is the aluminum-graphite composite of the composition 6, 9 and 12 wt% of the reinforcement. The design of experiments parameters considered is testing methods, a/W ratios and composition of the composite. All the three parameters and factors are put into Taguchi's L9 orthogonal array for analysis. The three dimensional modeling is done using the ANSYS software for simulation. The outcomes of the simulation are used to analyze process parameters. From the analysis, it is observed that the fracture toughness of the material is mainly influenced by the composition and a/W ratio, whereas the testing methods will have a least effect. The experimental, simulation and statistical results of fracture toughness agree with each other.
