a) ε=\(\frac{du}{dx}\)
b) ε=\(\frac{du}{d\epsilon}\)
c) x=\(\frac{d\epsilon}{du}\)
d) Cannot be determined
Answer: a
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=\(\frac{du}{dx}\)
