发展了立方准晶材料的断裂理论. 通过应用Fourier分析和对偶积分方程理论，得到了立方准晶材料Ⅲ型裂纹问题的精确解析解，并由此确定了位移与应力场，应力强度因子和应变能释放率. 结果表明，应力强度因子与材料常数无关，而应变能释放率依赖于所有的材料常数. 这些为研究此新固体材料的变形和断裂提供了重要的信息.

The fracture theory of cubic quasicrystal was developed. The exact analytic solution of a Mode Ⅲ Griffith crack in the material was obtained by using the Fourier transform and dual integral equations theory, and so the displacement and stress fields, the stress intensity factor and strain energy release rate were determined. The results show that the stress intensity factor is independent of material constants, and the strain energy release rate is dependent on all material constants. These provide important information for studying the deformation and fracture of the new solid material.
