Only the Poisson's ratio (NUXY) will be taken from the table. The ad-vantage of dealing with stress versus strain rather than load versus elongation is that the stress-strain curve is virtually independent of specimen dimensions. Also, it is concluded that the maximum true stress values are almost 15 higher than that of the maximum engineering stress values while the maximum true strain. 4b) that is identical in shape to the force-elongation curve can be plotted. Material properties like elastic modulus, Yield strength, etc will be taken from the stress-strain curve when it is available and not from the material properties table in the Material dialog box. engineering stress and strain, a stress-strain curve (Fig.
