摘要
基于准晶弹性流体动力学模型,采用有限差分法研究了含Griffith裂纹八次对称准晶在不同冲击载荷下的动态响应,得到了应力、位移和应力强度因子的数值结果,讨论了不同冲击载荷对动力学行为的影响.
In this paper,the dynamic response of an octagonal symmetry quasicrystals with a Griffith crack to different impact loading is investigated according to elasto-/hydrodynamic model. Using finite difference method, some numerical results of stress, displacement and stress intensity factors are obtained. The effects of different loading for the dynamic deformation behavior are discussed in detail.
