The experimental results showed that the dynamic strain has feature of cyclic creep. Cyclic loading affected the creep and creep speed.
结果显示动态应变呈循环蠕变状态，蠕变的大小、速度与循环应力幅值有关。
Based on the creep theory, the mechanical relationship of VSR and cyclic creep was discussed, and common factors such as stress amplitude, temperature and material properties were analyzed.
基于蠕变理论提出了振动时效与循环蠕变在力学本质上的相关性，并对交变应力幅、温度和材料特性等共同影响因素进行了分析。
In this paper, creep tests were carried out on annealed pure copper and normalized bronze containing Al under static and cyclic tension at room temperature.
