Simulation of mechanical behaviors of SiC reinforced Al matrix composites by finite element method

SUN Chao,SHEN Ru-juan,SONG Min (State Key Laboratory of Powder Metallurgy,Central South University,Changsha 410083,China)  
The effects of reinforcement shape,volume fraction and matrix type on the mechanical behaviors of Al matrix composites were studied by finite element method based on the axisymmetric unit cell model.The simulation results show that the addition of reinforcement particles can inhibit plastic flow of the ductile matrix and result in non-uniform deformation of the matrix,with the stress concentration presenting around the particle corner.The truncated cylinder-shaped SiC particles have the maximum inhibition on the plastic flow of the ductile matrix and result in higher load transferring ability of the reinforcements.When the volume fraction of reinforcements is small,the interfacial area between the SiC particles and the matrix increases with the volume fraction of the SiC particles increasing,and thus more load can be transferred from the soft matrix to the hard SiC particles.At the same time,the dislocation strengthening effect increases with the decrease of the particle interspacing.Different types of Al matrixes have different flow abilities.During the tensile deformation process,the composite with Al-Zn-Mg matrix has the highest strength due to the higher strength of Al-Zn-Mg matrix and more load transferred from the matrix to the reinforcement.
