Interaction between Circular Interfacial Crack and Screw Dislocation in 1D Hexagonal Quasicrystals
摘要
Abstract
The interaction effects between a single circular interfacial crack and screw dislocation loca-ted inside the matrix were investigated for 1D hexagonal quasicrystal.Through applying the complex po-tential method,the closed form solutions of this problem were obtained.The degradation results are con-sistent with the conclusions in previous literature.The stress intensity factor at the crack tip was also de-rived.The results show that the stress intensity factor decreases with the increase of the distance between the dislocation and interfacial crack.With the increase of the opening angle of the circular interfacial crack, the stress intensity factor increases firstly and then decreases.关键词
