Deformation velocity has no obvious effect on the flow of material, initial yield stress and flow stress.
变形速度对材料流动、初始屈服应力、流动应力影响不明显。
The effect of the definition of yield stress on the initial and subsequent yield surfaces.
不同屈服应力定义对初始屈服曲面的后继屈服曲面的影响;
The rate is also dependent on the initial stress level- as the stress approaches the yield strength, the rate increases.
松弛速率还取决于初始应力水平,当应力向屈服强度接近时,松弛速率增加。
