Question

True stress strain curve is also known as

(a) flow curve

(b) un-flow curve

(c) elastic curve

(d) parabolic curve

This question was posed to me in a job interview.

I'm obligated to ask this question of Behavior and Design Strength of Tension Members in portion Design of Tension Members of Design of Steel Structures

Answer 1

Correct choice is (a) flow curve

The best I can explain: True stress strain curve is also known as flow curve since it represents basic plastic flow characteristics if the material. Any point on the flow curve can be considered as local stress for metal strained in tension by magnitude shown on the curve.
