I was reading a journal article the other day (incidentally published by an indirect competitor of the company I work for) and found a flagrant error. They were claiming to achieve much higher elongation with a metal than should be possible for a specific additive manufacturing technique given the current state of the art. Skeptical I looked at their stress-strain curves and found the Young's modulus was closer to 30 GPa than 72 GPa as it should be for aluminum, which explains whey their elongation values are 2-3x higher than they should be. Basically they "stretched" the curve (flattened the curve one might even say).
Anyways does anyone else here have experience with contacting journal editors to tattle on bad papers? I'd rather avoid contacting the author of the paper.
