Lüders bands are the stripes of yielded metal that appear on mild steel when it is pulled past its yield point: instead of stretching evenly, the bar yields in a narrow band that then sweeps along it while the load stays almost flat. In this livestream Q/A, MES looks at what Lüders bands are, the upper and lower yield points behind them, and why they matter for steel sheet and engineering design.
If you have math or science related questions, I may have answers!

Try it: the Lüders Bands simulator shows a band forming and travelling along a steel bar, and the Mechanics of Materials Calculator draws the full stress-strain curve.
