Explain stress strain graph ?

Bro its very simple
First you should understand the terms in it
Thats is
1 ultimate strength
2 Yield strength
3 Breaking point
Definition in my own language
1 ultimate strength is the max extent at which the body do not deform . That is stress and strain is constant upto this point
2 yield stregth is the point at which the body deformed and the strain reduced at this point than ultimate strength and then increased.
3 Breaking point is the point at which the body fails
Now see the graph you can understand the graph
