摘要
利用复变方法,通过引入适当的保角变换,研究了一维六方准晶中狭长体双半无限共线快速传播裂纹动力学问题,得到了裂尖处的应力强度因子.在一些特殊条件下,狭长体双半无限共线快速传播裂纹动力学问题可以转化为静力学问题,通过极限运算,可以得到裂纹在裂尖处的应力强度因子,所得结果与已有的静力学结果一致.
By introducing the appropriate conformal transformation and using the complex variable function method,we study the double infinite coliner dynamics crack of the strip in one-dimensional hexagonal quasicrystals and get the dynamics SIFs at the crack tip. In some special conditions, the double infinite coliner dynamics crack of the strip can be turned into a static crack. By limitation computation,we can get the SIFs at the tip of the Griffith crack,which is in accordance with the known results.
