“metal fatigue”的概念、定义、习题解题方法及翻译-物理辞典

单词	metal fatigue
释义	metal fatigue A cumulative effect causing a metal to fail after repeated applications of stress, none of which exceeds the ultimate tensile strength. The fatigue strength (or fatigue limit ) is the stress that will cause failure after a specified number (usually 10⁷) of cycles. The number of cycles required to produce failure decreases as the level of stress or strain increases. Other factors, such as corrosion, also reduce the fatigue life
