What's Inside the Box? – Length‐Scales that Govern Fracture Processes of Polymer Fibers
Open accessAbstract
This work shows that multiple length-scales must be considered concurrently to explain a polymer fiber's impressive mechanical performance and resilience. The considerations of interatomic interactions alone cannot explain the fracture strength observed in biological fibers. Instead, the fracture strength of a fiber depends strongly on the length-scale of observation, including a fiber's sensitivity with respect to cracks and other flaws.

Natural design in limpet teeth is optimized towards theoretical strength limits.
“suggesting that natural design in limpet teeth is optimized towards theoretical strength limits.”
From Extreme strength observed in limpet teeth (2015) · cites this paper as [35]
The Connecting the Length Scales section discusses how hierarchical structures help natural fibers retain strength, and the paper discusses a theoretical strength limit for flaw-free fibers. Neither passage addresses limpet teeth or says their design is optimized toward that limit. Searches for limpet teeth, radula, and the claimed optimization found no relevant passage in our copy; page numbers were not available. (LLM, conf=0.76)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
