Description
Summary:According to the dynamic behavior characteristics of SiCp/Al composites, the constitutive equation of high volume fraction composites is established by SHPB dynamic compression test, shear lag model and effective medium approximation method, and the calculation results are in good agreement with the experiments. The established constitutive equation is then imported into Abaqus to establish a three-dimensional cutting simulation model, which is combined with cutting experiments to analyze the dynamic removal mechanism of material during the cutting process and the cutting surface formation process. The results show that the formation and propagation of holes and cracks play an important role in the formation of chips. The failure removal mode of SiC particles is an important factor affecting the cutting surface morphology. The research results provide an important theoretical basis and research means for the study of cutting mechanism of SiCp/Al composites with high volume fraction.
