[最新] yield stress graph 801616-Yield stress graph

The stress at the yield point is called the yield strength, S ty For materials without a welldefined yield point, it is typically defined using the 02% offset method in which a line parallel to the linear portion of the curve is drawn that intersects the xaxis at a strain value of 0002The curves of Figs 16 and 17 are drawn with the stress defined as load divided by original area of crosssection and the longitudinal strain is defined as δl/l 0, where l 0 is the original length of test specimen The curves would look very much different if we use true stress on ordinate and true strain on abscissa The true stress and true strain are defined below For accurate calculations, the true stresstrue strain curve for the metal should be drawn to determine the yield strengthOffset yield strength is the stress that will cause a specified amount of permanent strain (typically 02 percent) It is found by drawing a line that crosses the X (strain) axis at 0002 and runs parallel to the stressstrain line (slope = E) The point where this line intersects the stressstrain curve is the offset yield point
