| Abstract | In this paper, the deformation, fracture and damage behavior of SiCp/Al composites are studied by experiments and finite element analysis. The crack cracking process of the material was observed by in-situ tensile test, it was found that the composite first produced microcracks near the particles, and the cracks mainly spread to depth and then to both sides. It is determined by a tensile test that the fracture mechanism of the material is the tearing of the aluminum matrix and the peeling between the particles and the matrix. The tensile damage mechanism of the composite material in three directions (rolling direction, rolling transverse direction and rolling normal direction) and different strains were determined. It is found that in the process of tensile deformation, microcracks are first formed at the defects (voids) and weak interfaces, and many fine cracks converge together to form large cracks leading to the fracture of the material, during which a few particles fall off, but there is no particle fracture. The global and local tensile tests of the composites were simulated by finite element method, the results of the stress-strain state under different strains and the effects of particles on the materials are analyzed in detail, and the validity of the test results is determined. |
