The value of true strain produced in compressing a cylinder

Home » Materials Science and Manufacturing Engineering » Materials Science and Manufacturing Engineering Miscellaneous » Question

The value of true strain produced in compressing a cylinder to half its original length is

1. 0.69
2. -0.69
3. 0.5
4. -0.5

Correct Option: B

Engg. strain

(ε) =	Change in Length
	Original Length

True strain = ln(1 + ε) = ln(1 – 0.5) = – 0.69
