Calculation for Stress-strain carves:

 

528_Stress-strain carves for ductile materials.png

After reaching point D, if bar is strained further, a local reduction in cross section occurs in gauge length (that is, formation of neck). At this neck stress increases with decrease in area at constant load, till failure take place. Point F is called as 'rupture point. Note that all the stresses are based on original area of cross section in drawing curve of the given figure.
