Abstract:In this paper,by using the generalized complex variable function method,the problem about a parabolic crack in one-dimensional orthorhombic quasicrystals periodical plane was considered.To solve this problem by proposing the generalized conformal mapping the exterior of the parabolic crack in the physical plane was mapped onto the inner of the a unit circle in the mathematical plane.Complex representation of stress in the phonon field and phason field was got in the mathematical plane and the parabolic crack of SIFs at the crack tip were obtained.Under the special condition the result is similar to the SIFs at Griffith crack.
Keywords:one-dimensional orthorhombic quasicrystals materials  parabolic crack  generalized conformal mapping  stress intensity factor
