摘要
提出了一种可以综合利用以往积累的试验数据测试机械工程材料裂纹扩展曲线的新方法 ,与传统的只能利用当前试验数据确定机械工程材料裂纹扩展曲线方法相比 ,在精度相同的情况下 ,可以节省大量试件 ,而且在试样数一定的情况下 ,又可大大提高预测精度。
A new method for testing crack growth curve of mechanical engineering materials is presented in the paper The information that can be used in this method is much more than that in the traditional methods, because this method can make full use of the current test data and the previous data, while the traditional method can only use current test data Thus, fewer specimens are required in this method and the result is more accurate for the small number of specimens An experimental contrast example is also given in the paper
