WebJun 23, 2024 · The true stress-strain curve is ideal for material property analysis (meant research or study). For everyone except (some) materials scientists, the engineering stress-strain curve is simply more useful than the true stress-strain curve. However, the true stress-strain curve is ideal for showing the actual strain (and strength) of the material. WebThe yield point is the point on a stress-strain curve that indicates the limit of elastic behavior and the beginning plastic behavior. Yield strength or yield stress is the material property defined as the stress at which a …
