A material behaves in certain ways above and below the proportional limit on a stress strin curve, which of the following is correct______________?
Correct answer: A. Above the proportional limit a material function in a plastic manner, while below the proportional limit it behaves as an elastic
- A. Above the proportional limit a material function in a plastic manner, while below the proportional limit it behaves as an elastic
- B. Above the proportional limit a material functions in an elastic manner, while below the proportional limit it behaves as an plastic
- C. Either A or B
- D. Neither A or BConsult Online Doctors
Explanation
Below the proportional limit, stress is directly proportional to strain and the material returns to its original form, so behaviour is elastic. Beyond this limit, permanent deformation begins and the material behaves plastically, making option A correct.
