| Abstract: |
| The scattering of SH wave in one-dimensional hexagonal quasicrystal with a linear crack is studyed in the paper.By using the intergral transform technique and combining with Copson methods,through solving dual integral equations,the analytical expression of phonon field stresses,phason field stresses,phonon field displacements,phason field displacements and dynamic stress intensity factor at crack tip are obtained.Numerical examples are used to discuss the impact of the crack length,incident angle,incident wave frequencies on dynamic stress intensity factors.The research has certain value in engineering materials application. |
