Question

Which of the following statement is correct?

(a) stress and strain calculated using initial cross section area and initial gauge length are referred to as true stress and true strain

(b) stress and strain calculated using current cross section area and initial gauge length are referred to as true stress and engineering strain

(c) stress and strain calculated using initial cross section area and initial gauge length are referred to as engineering stress and engineering strain

(d) stress and strain calculated using current cross section area and gauge length are referred to as engineering stress and engineering strain

This question was addressed to me in an interview for job.

The above asked question is from Behavior and Design Strength of Tension Members topic in section Design of Tension Members of Design of Steel Structures

Answer 1

Correct choice is (c) stress and strain calculated using initial cross section area and initial gauge length are referred to as engineering stress and engineering strain

Easiest explanation: Stress and strain calculated using initial cross section area and initial gauge length are referred to as engineering stress and engineering strain. Stress and strain calculated using current cross section area and gauge length are referred to as true stress and true strain.
