Question

Explain stress with the help of a diagram...?

Answer 1

$\Large{\red{\underline{\underline{\tt{AnSweR:}}}}}$

◆ Stress vs strain graph -

This graph can be explained with different areas -

1) Elastic region - graph in this region is linear.

2) Yielding region - graph becomes curve in this region.

3) Strain hardening - graph is descending in this region until breaking point.

4) Necking & failure - end of starts to show necking & it breaks.

[Refer to the image for labelled diagram of stress-strain curve.]

Hope this helped. Thanks for asking..
