What's inside the box? - Length-scales that govern fracture processes of polymer fibers.

Tristan Giesa¹, Nicola M Pugno, Joyce Y Wong, David L Kaplan, Markus J Buehler.

Abstract

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.
