摘要
将有限差分法应用到含Griffith裂纹八次对称二维准晶的动力学问题中,用有限差分法离散弹性—流体动力学模型得到了3种不同载荷下应力强度因子随时间变化的规律.
In this paper,the finite difference method was used in the fracture problem of a octagonal quasicrystals with a mode_I Griffith crack.By using the finite difference method to discretize elasto-hydrodanamics mode,the regular pattern of stress intensity factors on the 3.different dynamic loadings following the change of time was expounded.
