direct stress is based on the value obtained by dividing the load by originalcross-sectional area. That is the reason why the value of stress started dropping after neck is formedin mild steel (or any ductile material).But actually as material is stressed itscross-sectional area changes. We should divide load by the actual cross-sectional area to get truestress in the material. To distinguish between the two values we introduce the terms nominal stress and true stress
True Stress =Load/ActualCross-sectionalArea
Nominal Stress =Load/Original Cross-sectionalArea

Why true stress higher than the nominal stress?
nominal stress is the engineering stress, which is the force divided by the original Area. true stress is the force divided by the area of the deformed specimen as it deforms. Since the area of the deformed specimen is usually smaller than the original area true stress is higher than the nominal stress... Ali D
