【摘要】 分别用Ｍａｎｓｏｎ－Ｃｏｆｆｉｎ和Ｆｕ＇ｓ公式对合金钢、铝合金、钛合金等航空常用材料不同状态的４０多条ε—Ｎ曲线试验数据进行了分析、处理，结果表明，Ｆｅ＇ｓ公式不但可以简化试验，而且能更好地拟合ε—Ｎ曲线试验数据。更多还原

【Abstract】 In this paper, the experimental data of more than 40 ε-N curves were treated bv theManson-Cof-fin formula and the Fu’s formula respectively. The results have showed that Fu’s formula is better than Manson-Coffin formula.更多还原
