In this paper, the problem definition of and the numerical procedures of smoothed particle hydrodynamics (SPH) on the analysis of semi-solid forming process of Al-SiC functionally graded material (FGM). FGMs are know to have many advanced features such as the reduction of thermal stress, enhanced resistance to wear, etc. However, Al-SiC FGM which is manufactured by a centrifugal method is difficult to machine. Thus, a semi-solid forming as a near net shape process has been attempted. SPH is used to clarify the flow of melt containing solid phase as distributed particles.
