Yield strength point on graph 178389
Hooke's Law and Stressstrain Curve The point B in the curve is the Yield Point or the elastic limit and the corresponding stress is the Yield Strength (S y) of the material Once the load is increased further, the stress starting exceeding the Yield Strength This means that the strain increases rapidly even for a small change in the stressThe stress at the point where the stressstrain curve deviates from proportionality is the yield strength of the material Some plastics' deformation is linearly elastic and once the maximum strength is attained, the material fracturesThis aligns with the start of the strain hardening region in the stressstrain graph The yield strength point is where the plastic deformation of the material is first observed If the material is unclamped from the testing machine beyond this point, it will not return to its original length What Is Tensile Testing Instron Yield strength point on graph
