Chapter 8, Problem 8.7P

Interpretation Introduction

Interpretation:

The graph of true stress v/s true strain is given. In which total imposed strain of $\xi =0.1,0.2,0.3and0.4$.

The elastic and plastic component of strain needs to be determined. Modulus of elasticity of metal is 100 GPa.

Concept introduction:

If the value of true stress depends on the actual cross-sectional area of specimen then, stress-strain curve increases with fracture. But if strain measurement is based on instantaneous, the curve obtained is called true-stress true strain curve.
