| 摘 要： | 本文分别采用 Manson—Coffin 公式和 Fu's 公式,对8条铝合金材料ε—N 曲线试验数据进行了分析、处理,并对两种公式所处理试验数据的绝对误差和相对误差作了比较。结果表明,Fu's 公式比著名的 Manson—Coffin 公式能更好地描述铝合金材料ε—N 曲线。而且 Fu's 公式还简化了ε—N 曲线的测试工作。

| Abstract: | In this paper.these test datas of 8ε—N curves for aluminium alloys are analysed and treated by the Manson-coffin formula and Fu's formula,respectively.And two abso- lute errors and relative errors which is treated by these formulas are compared with one another.It is showed that the Fu's formula is better than the Manson-coffin formula to describe these ε—N curves for aluminium alloys.The Fu's formula also simplifies the tests for ε—N curves. |
