By using the method of stress functions, the problem of mode-II Griffith crack in decagonal quasicrystals was solved. First, the crack problem of two-dimensional quasicrystals was decomposed
into a plane strain state problem superposed on anti-plane state problem and secondly, by introducing stress functions, the18 basic elasticity equations on coupling phonon-phason field of decagonal quasicrystals were reduced to a single higher-order
partial differential equations. The solution of this equation under mixed boundary conditions of mode-II Griffith crack was obtained in terms of Fourier transform and dual integral equations methods. All components of stresses
and displacements can be expressed by elemental functions and the stress intensity factor and the strain energy release rate
were determined.
