中文摘要:
      在腐蚀环境下飞机结构耐久性分析的相对小裂纹范围内, 研究了不同指定裂纹尺寸对应的裂纹萌生寿命预腐蚀影响系数模型。对比分析了4种函数形式对 (C, t) 数据的拟合, 结果表明单参数指数函数形式拟合效果最好, 不同裂纹尺寸的C-t曲线参数无显著差异。
英文摘要:
      Within the range of small crack during analysis of aircraft structural durability under corrosion environment, the model of pre-corrosion crack initiation life influence coefficient at different crack sizes was studied. The data of (C,t) was fitted with four forms of function, and then the fitting results were compared and analyzed. The result showed that the single parameter exponent form of the function is the best and the slopes of these curves have no difference.
