Question

Strain displacement relation ______

(a) ε=\(\frac{du}{dx}\)

(b) ε=\(\frac{du}{d\epsilon}\)

(c) x=\(\frac{d\epsilon}{du}\)

(d) Cannot be determined

I got this question in final exam.

The above asked question is from One Dimensional Problems topic in section One Dimensional Problems of Finite Element Method

Answer 1

Correct option is (a) ε=\(\frac{du}{dx}\)

Explanation: The relationship is that connects the displacement fields with the strain is called strain – displacement relationship. If strain is ε then strain – displacement relation is

  ε=\(\frac{du}{dx}\)
