提出了一种求解三维二十面体准晶弹性问题的摄动方法。考虑无限大三维二十面体准晶受圆形裂纹削弱的情形，得到了I型载荷下直到O（R2）的一致有效渐近解，其中R是声子-相子耦合的弹性常数.
Perturbation method for solving elastic three-dimensional (3D) problems for 3D icosahedral quasicrystals is proposed. Considering an infinite 3D icosahedral quasicrystal weakened by a circular crack, we obtain the uniformly valid asymptotic solutions up to O(R2) for the mode I loading, where R is the elastic constant of phonon-phason coupling.
