摘要
利用当前通用的计算机编程技术,以高级编程语言VB为制作工具,以Origin7.0为作图工具,绘制了铸造Ti-6Al-4V钛合金疲劳裂纹扩展曲线。采用该编程技术,实现了参数的随机输入和曲线的动态形成,真实地制作了不同应力比下的疲劳裂纹扩展速率（da/dn）与裂纹尖端应力强度因子（ΔK）的关系曲线。同时该方法极大地提高了数据处理的效率及准确性。
The fatigue crack propagation curves of Ti-6AI-4V casting titanium alloy were plotted by using the universal computer language-VB and Origin7.0.The random input of the data and the dynamic formation of curve could be realized, and the curves of the fadgue crack growth rate （da/dn） and stress intensity factor （AK） at different stress ratio were obtained. Meanwhile this method improved the efficiency of data processing and the accuracy of the results.
