Stress-Strain Graph:Why Plot Strain~Stress?

Click For Summary
The discussion centers on the confusion regarding the conventional plotting of strain against stress in stress-strain graphs, where stress is often considered the independent variable and strain the dependent variable. Participants explain that this convention is rooted in material behavior, as stress typically influences strain in elastic and plastic deformation. The area under the stress-strain curve represents the elastic energy stored in the material, which is a key concept in material science. While some argue for a stress versus strain plot, the established convention remains due to its practical applications in engineering and materials testing. Ultimately, the choice of plotting strain against stress is based on historical usage and the relationship between the two variables in material behavior.

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?

I need to anneal 5052 aluminum for a home project. Google has given me mixed results on how to do this. Short version is that I'm doing some heavy forming on a piece of 5052-H32 and I'm running into issues with it work hardening. I've tried the Sharpie trick with a propane torch. But I'm not sure this is doing anything. I'm also seeing conflicting opinions whether to quench or air cool. So I'm looking for some expert opinions. (Oven heating is not an option due to size.) Thanks. edit: The...
