New paper: “Similarity of internal and external friction: Soft matter frictional instabilities obey mean field dissipation through slip avalanches”

We usually think of hydrogels as slippery and wet — that’s their definition! But if a probe pushes on them to a higher pressure before applying lateral slip, that high pressure causes unstable friction, or stick-slip (just like the elastomer in our prior post!). So even inherently low-friction materials relieve interfacial strain in extreme ways. […]
