摘要

基于扩展有限元方法研究钛合金传统机加接头耳片与含预置非焊合区的层合接头耳片结构在拉- 拉疲劳荷载作用下的裂纹扩展特性，揭示螺栓孔在受挤压情况下非焊合区对钛合金典型连接结构疲劳裂纹扩展的抑制作用，并通过试验验证扩展有限元方法对钛合金典型连接耳片结构裂纹扩展特性分析的有效性。

Abstract

The fatigue crack growth characteristics of the traditional lug and diffusion bonded lug with localized non-welded area of TC4 titanium-alloy are studied

and the simulation techniques based on extended finite element method (XFEM) under tension-tension cyclic loading are used

in order to reveal the inhibitory effect of non-welded area on crack growth when the bolt hole is in the extrusion. The comparisons of the numerical results and the experimental results show that the extended finite element method (XFEM) is an effective numerical method for the fatigue crack growth characteristics analysis.
