The so-called stress-strain curve in engineering is usually the nominal stress-strain curve.However,this kind of curve is only approximate,which only provides a reference to actual engineering problems.The true stress-strain curve of the widely used metal material-Q235 was obtained,through the expe...
Artificial muscles are indispensable components for next-generation robotics capable of mimicking sophisticated movements of living systems. However, an optimal combination of actuation parameters, including strain, stress, energy density and high mechan
The point of intersection of elastic line and plastic line moves toward the low cycle life with the hardness of the spring steel raised after tempering from the strain fatigue curve. 在应变疲劳曲线上,弹性线和塑性线的交点随弹簧钢回火后硬度的升高而向低循环寿命移动; 27. 23kb Nickel steel is...
