Abstract

Today, with the advancement of technology, new engineering materials with higher qualities are needed more and more. Composites are introduced as new materials to the industry. Over time, various types of composites have been synthesized with different reinforcing materials. The prominent properties of these materials include low fatigue resistance, low density, and very good strength. Aluminum matrix composites have attracted much attention in recent years. These lightweight composites exhibit good resistance to stress, and noticeably better corrosion resistance. The study of failure and crack growth in these composites under different conditions can help predict when the composite coating should be repaired or replaced. Also, these data can be used to improve properties of composites. In the present study, we found that in metal matrix composites, crack growth mechanisms depend on the shape, size, orientation, and distribution of the reinforced particles. In the simulated specimen, the particles far away from the crack tip were able to withstand stress. The particles closer to the crack tip were broken down. Composites with unique strength and properties will definitely be the future of the coatings. Various industries in the country need to research in this field more than ever.
