Abstract:The Mori-Tanaka method based on spring-type imperfect interface used to study the effective elastic properties of one-dimensional orthogonal quasicrystal composite materials.Explicit expressions for the effective elastic constants of phonon field,phason field,and phonon-phason coupling field are given.The effects of the aspect ratio and volume fraction of inclusions on the effective elastic constants of quasicrystal composite materials are discussed in detail.The results indicate that considering imperfect interfaces reduces the effective elastic constants to some extent.
Key words:spring-type imperfect interfaces; one-dimensional orthogonal quasicrystal; the Mori-Tanaka method; inclusions
