Yield Strength Definition Stress Strain Graph Stress Strain Graph Explanation Yield Strength Graph What is Yield Strength?RambergOsgood Equation The stressstrain curve is approximated using the RambergOsgood equation, which calculates the total strain (elastic and plastic) as a function of stress where σ is the value of stress, E is the elastic modulus of the material, S ty is the tensile yield strength of the material, and n is the strain hardening exponent of the material which can be calculated based onUniaxial (1D) stress In the case of uniaxial stress or simple tension, ≠, = =, the von Mises criterion simply reduces to =, which means the material starts to yield when reaches the yield strength of the material , in agreement with the definition of tensile (or compressive) yield strength Multiaxial (2D or 3D) stress An equivalent tensile stress or equivalent von Mises stress, is used Tensile Testing Alex S Web Page Yield stress calculation online
