Chapter 8, Problem 8.12P

Interpretation Introduction

Interpretation:

The strain-hardening exponent for the metal from the given true stress-true strain curve should be determined.

Concept introduction:

Stress-strain relation is given by:

${\text{σ = kξ}}^{\text{n}}$

Where,

$\begin{array}{l}\begin{array}{l}\text{σ = Stress}\hfill \\ \text{ξ = Strain}\hfill \\ \text{k = Strength coefficient}\hfill \end{array}\\ \text{n = Work hardening coefficient}\end{array}$
