对于要考察抗疲劳性能的金属构件(部件),往往采用应力寿命法,基干标准曲线及腐蚀疲劳修正曲线来进行疲劳分析。然而环境是千变万化的,要针对特定环境——获得这种修正曲线耗费很大。人们希望了解承受循环载荷的构件—环境系统是不是一个腐蚀疲劳系统,并期望建立起腐蚀疲劳免于发生的条件,把问题简化为单一的疲劳问题。从本文引用的文献可知,动态循环塑性变形强化了软钢在交变的拉伸和压缩应
For the metal components (components) to be investigated for fatigue resistance, fatigue analysis is often performed using the stress life method, the standard curve of the stem and the corrosion fatigue correction curve. However, the environment is ever-changing, and for a specific environment - it can be costly to obtain this correction curve. It is hoped that understanding the components subjected to cyclic loading - whether the environmental system is a corrosive fatigue system and is expected to establish the conditions under which corrosion fatigue will not occur, simplifies the problem to a single fatigue problem. From the literature cited in this paper, it can be seen that the dynamic cyclic plastic deformation strengthens the soft steel in alternating tensile and compressive
