摘要
分析了金属在常温状态受弹性应力作用时微量塑性变形的机理，从变形积累的角度出发进一步分析了金属结构在长期弹性载荷下因产生宏观永久变形而失效的原因。
This paper analizes the micro-plastic deformation mechanism of metals under e lastic stress service. From the point of view of deformation accumulation,the reason of micro-per manent deformation of metal structure under long-term elastic elastic stress service is analized.
