Question
In a stress strain curve for a viscoeleastic material the proportional limit is?
The point where the plastic region equals the elastic region.
The point where stress is no longer proportional to strain.
The point where the yield point equals the elastic limit.
None of the above is correct.
a.The point where the plastic region equals the elastic region.
b.The point where stress is no longer proportional to strain.
c.The point where the yield point equals the elastic limit.
d.None of the above is correct.
Explanation / Answer
B) is the correct answer.
Because for proportional limit , stress is directly proportional to strain.
