在试验的基础上研究了 30 Cr2 Mo V钢在常温下的循环应力应变特性。得到了该材料的低周疲劳特性参数、循环应力 -应变曲线和具有 95 %置信度的不同存活率下的应变 -寿命曲线。图 9表 3参 4
Based on the experiment, the cyclic stress-strain characteristics of 30 Cr2 Mo V steel at room temperature were studied. The low-cycle fatigue characteristics of the material, the cyclic stress-strain curve and the strain-life curve at different survivals with 95% confidence are obtained. Figure 9 Table 3 Senate 4
