I am trying to calculate the static yield stress of a specimen using the 0.2% offset line on a stress strain curve. I found the static yield stress of the specimen to be the number in bold (104.1239). Given the shape of the graph and how close the static yield stress appears to be to the UTS, I was wondering if this value actually looked correct? Or could I have accidentally calculated the dynamic yield stress instead?
The material I used in this test was a "low grade aluminum"... which is throwing my thought process off.
I would really appreciate any insight on this.
