- TL;DR Summary
- Is the maximum strain of a sample undergoing a tensile test proportional to its cross-sectional area? I think the answer is no, but my data say the answer is yes.
I would assume that because the samples are made of the same material they would fail at the same stress and so the same strain. However, the data shows that the sample with a greater cross-sectional area fails at a greater strain, and the two are roughly proportional. Does anyone know what might be going on there? (For more context, it's two brass samples and they underwent significant plastic deformation).
