Web0.2% Offset Yield Strength (stress) The stress at the intersection of the stress-strain curve and a straight line with slope of E and beginning at 0.002 (0.2%) on the strain axis. The most satisfactory definition of yield strength for aluminum alloys and many other materials. Note: At this definition of yield, the plastic portion of the strain is WebWhen the bulk stress increases, the bulk strain increases in response, in accordance with Equation 12.33. The proportionality constant in this relation is called the bulk modulus, B, or 12.39 The minus sign that appears in Equation 12.39 is for consistency, to ensure that B is a positive quantity.
