Study on the effective elastic performance of composites containing decagonal symmetric two-dimensional quasicrystal coatings

On account of the Mori-Tanaka approach, the effective elastic performance of composites containing decagonal symmetric two-dimensional (2D) quasicrystal (QC) coatings is studied. Explicit expressions for the effective elastic constants of rare-earth QC reinforced magnesium-based composites are provided. Detailed discussion is presented on the effects of the volume fraction of the inclusions, the aspect ratio of the inclusions, the coating thickness, and the coating material parameters on the effective elastic constants of the composites. The results indicate that considering the coating increases the effective elastic constants of the composites to some extent.
