Stress-strain curve at slow loading-rate obtained in alternating loading rate test is shifted along the unloading curves, and then it overlapped on stress-strain curve at a fast loading rate.
将在交替变换荷载速率试验中得到的对应于低荷载速率的应力–应变曲线沿着卸载曲线平移，可以与高荷载速率对应的应力–应变曲线重合。
The dies are subject to alternating stresses due to loading and unloading during the deformation process and this causes crack initiation and eventual failure.
在变形加工过程中，由于加载、减载、模具承受交变应力作用，这就将引起开裂并发生重大破坏。
