NEW METHOD OF BUILDING CONSTITUTIVE EQUATION OF METAL MATRIX COMPOSITES REINFORCED BY SiC PARTICLES

The expert system based on artificial neural network was used, and the constitutive equation of PRMMCs was built. After training the network with experimental data which was investigated by the application of a thermecmasor simulator for hot working, it can correctly predict the relationship between process parameters and flow stress. The deviation of the analytical results from the experimental data is less than 10%.
