eFatigue - Glossary Cyclic Stress-Strain Curve

The cyclic stress strain curve is a plot of all of this data.The curve describes the behavior of the material after it has been plastically deformed.This behavior is usually different than the initial behavior that is measured in a traditional tensile test.A simple power function is fit to this curve to obtain three material properties eFatigue - Constant Amplitude Strain-Life TechnicalThe cyclic stress strain curve is a plot of all of this data.The cyclic stress strain curve describes the behavior of the material after it has been plastically deformed in service a few times.You can think of the traditional stress strain curve as describing the behavior of the material as it was manufactured.This kind of information is not available for free on the Internet.You can conduct a search of this site - many requests have been made for S-N cuYou can find fatigue information for many materials for free at fatiguecalculator. You can generate an S/N curve with just the fatigue s1Gerry,Actually,I was able to find the fatigue values for this material in a paper on the internet at http://fac ta.junis.n i.ac.yu/fa cta/macar/Gerry,For 42CrMo4,sigma f' =1154 MPa b1 = -.061 To plot the S/N curve plot cycle counts versus calcuated stress amplitude,where stress amplituThanks chaps for your helpful information. I was going to try to convert this data into a 'rolling contact SN curve' for use in a brg application.Rolling contact fatigue is highly dependent upon surface roughness,inclusion type and amount,case hardness,case microstructure (non-martensiticI would agree with TVP.I would not recommend using S/N fatigue data obtained from reverse bending,uniaxial loading and attempt to extrapolate thiHysteresis,Temperature and Resistance MeasurementsMechanical stress-strain hysteresis,temperature and electrical resistance measurements were performed for the detailed characterisation of the fatigue behaviour of the quenched and tempered steel SAE 4140 (42CrMo4) under constant amplitude loading and service loading.On

Tangent Modulus Tangent modulus is defined as the slope of a line tangent to the stress-strain curve at a point of interest.Tangent modulus can have different values depending on the point at which it is determined.For example,tangent modulus is equal to the Young's Modulus when the point of tangency falls within the linear range of the stress-strain curve.Properties of Materials - Aerospace EngineeringTangent Modulus Tangent modulus is defined as the slope of a line tangent to the stress-strain curve at a point of interest.Tangent modulus can have different values depending on the point at which it is determined.For example,tangent modulus is equal to the Young's Modulus when the point of tangency falls within the linear range of the stress-strain curve.Modelling,identification and application of shear strain at an equivalent strain rate of 10 2 s 42crmo4 stress strain curve#255;1 for the 42CrMo4-BA steel.Fig.3.Evolution of (a) the compressive stress as a function of the plastic strain and (b) the shear stress as a function of the plastic shear strain,at 20 42crmo4 stress strain curve#176;C,600 42crmo4 stress strain curve#176;C and 1000 42crmo4 stress strain curve#176;C,for different equivalent strain rates for the 42CrMo4
