Stress-Strain Graph:Why Plot Strain~Stress?

[haraigcar]

I have a very fundamental doubt regarding the stress strain graph for many materials..Normally we plot strain ~stress in the graph..but it seems that stress is the independent variable and strain is the dependent variable..but still why nowhere i have found the curve as stress~strain..can anybody please tell me the reason?

Because the elastic stored energy is the area under the sigma (y axis) - epsilon (x axis) graph if we plot it that way round.

See the discussion in this thread.
