Engineering stress vs true stress?5/29/2023 ![]() If excessive decrease (or increase) in the cross sectional area occurs, then the force should be divided by the actual area (area after deformation) to obtain the “True Stress”: In this case, the stress is termed the “Engineering Stress”. ![]() Other Measures of Stress Engineering vs True Stress:ĭuring material uniaxial tests, the value of the applied stress is obtained by dividing the applied force by the measured initial cross sectional area of the specimen.
