本文通过引入位移函数使得立方准晶的轴对称弹性问题化为求解一高阶偏微分方程.作为轴对称问题的例子,得到了立方准晶含有圆盘状裂纹时其弹性场的分析解,并由此确定了应力强度因子和能量释放率.

Axisymmetric elasticity problem of cubic quasicrystal is reduced to a solution of a partial differential equation with higher-order by introducing displacement function. As an example of axisymmetric elasticity problem, the analytic solutions of elastic field of cubic quasicrystal with a penny-shaped crack are obtained, and the stress intensity factor and strain energy release rate are determined.
