Which stress-strain relationship is preferred for accurately predicting the behavior of materials under high strains?

9. Which stress-strain relationship is preferred for accurately predicting the behavior of materials under high strains?

1. Engineering stress and strain
2. True stress and strain
3. Nominal stress and strain
4. Hooke's Law

Answer

The correct answer is: B) True stress and strain

Explanation

True stress and strain provide a more accurate representation of material behavior under high strains because they consider the changing dimensions of the material.
