Abstract
The finite element analysis based on microstructure of SiCp (silicon carbide particulates) reinforced aluminum matrix composites to evaluate the dynamic mechanical response and damage behavior was carried out. The effects of strain rate, reinforcement content and reinforcement size on the stress-strain state of SiCp reinforced aluminum matrix composites and the damage mechanism were analyzed. The results show that the strain rate sensitivity of the composites is obvious, and this trend is promoted with the increase of SiCp content and the decrease of reinforcement size. The damage such as particle breakage and interface debonding was predicted, and the influence of reinforcement size on the damage mechanism was analyzed. It is found that the defects of the composites with smaller reinforcement particle size are mainly SiCp/Al interface debonding, while SiCp cracks and interface debonding are more likely to coexist in the composites with larger reinforcement size.
