Explain stress versus strain graph with the help of a neat labelled diagram.
Answers
Hey Pruthvi,
◆ 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..
Answer:
The stress vs strain curve helps to understand physical behavior of solids on stretching.
Initial part of the graph is linear ; this is the elastic region where stress is proportional to strain. The slope gives us the Young's Modulus.
In the next part, we get the Plastic region. If the stretch force is removed, the solid might not return to its original length (deformations take place)
Finally we get Fracture point or Rupture Point where the solid is unable to withstand any further increase in stress.
