Hi Forum,
I´m happy I found this forum...
I hope someone can answer my (simple) question:
According to this thread https://www.physicsforums.com/threads/calculating-0-2-proof-stress-of-aluminium.206648/ on page 2 the stress/strain diagram is not the same as force/elongation.
Due to the constant area surface and the constant start length, the graphs look the same.
Now the question:
Am I wrong when I use the force/elongation graph for further studies? (e.g. Yiel point 0.2% determination). Or did I miss another influence?
Background:
We build bending machines and need to find out the Yield point of mainly Aluminium material. The parameters we have can gather are:
- Force
- position (length)
- Time (Speed)
- We can input length and areal surface in a programmed mask
Thank´s a lot and excuse my maybe too simple question...
