Webb8 feb. 2024 · The yield strength at 0.2% offset is determined by finding the intersection of the stress-strain curve with a line parallel to the initial slope of the curve and which intercepts the abscissa at 0.2% Why 0.2 offset is used to find the value of yield strength? http://engineeringarchives.com/les_mom_offsetyieldmethod.html

WebbDifferent values may be obtained if tangents are drawn at different points. Therefore, an offset yield point is obtained at a strain of 0.002 (0.2%). A straight line is drawn parallel to initial portion of stress-strain curve at the strain value of 0.002 and the point where it intersects the stress-strain curve is taken as yield point.
