Question

Which of the following statement is TRUE ?

• A. True stress is always less than the engineering stress in the
• B. True stress is always greater than the engineering stress in the plastic region
• C. True stress is equal to the engineering stress in the plastic
• D. True stress is always less than the engineering stress in the elastic region

Answer 1

Answer:

B. True stress is always greater than the engineering stress in the plastic region

True stress and engineering stress are two different ways of measuring the stress in a material. True stress is defined as the force per unit area of the material at the instant of deformation, while engineering stress is defined as the force per unit area of the material in its original state.True stress is always greater than the engineering stress in the plastic region
