Thanks! It’s all coming together now. If you can find some finite element results and point out a few articles that would be great.

How would you explain the fact that a notched specimen* of a ductile metal becomes brittle when tested uniaxially? The notch produces three axial tensions. But why does three axial tension cause brittleness? And how does the tension distribution look like in the notched area? Thanks...

If you look at a engineering stress-strain curve compared to the true* stress-strain curve of a steel for example, they start to differ somewhere after the yield point. Before the yield point they seem to be the same. If you look at the specimen in the in the elastic region, as it deforms...
