WebSep 28, 2024 · To determine the flow behavior of SUS304 stainless steel under different conditions, axisymmetric compression tests were conducted over a wide range of forming temperatures (25 °C to 400 °C) and strain rates (10−3 to 10 s−1). Flow curves were obtained for different forming conditions to study the influence of the forming temperature … WebAug 28, 2024 · When such elastic elements reach their critical strain, the structure starts to break down causing shear thinning (strain softening) and subsequent flow. This event corresponds with a peak value in shear stress, which is equivalent to the yield stress, before leveling off to its equilibrium value. This is illustrated in Figure 7. Figure 7.
