Creep, stick-slip, and dry-friction dynamics: Experiments and a heuristic model.
TL;DR: An extensive study of the dry-friction dynamics of a paper-on-paper system and proposes a heuristic model of low-velocity friction based on two main ingredients, which assumes that the dynamics is controlled by the Brownian motion of an effective creeping volume in a pinning potential, the strength of which increases with age.

Ultrasound Propagation in Externally Stressed Granular Media
TL;DR: In this paper, the coexistence of a coherent ballistic pulse traveling through an effective contact medium and a speckle-like multiply scattered signal was observed in pulsed ultrasonic transmission through granular glass beads under oedometric loading.
Self-healing slip pulses along a gel/glass interface.
TL;DR: Experimental evidence of self-healing shear cracks at a gel/glass interface is presented, and this system exhibits complex spatiotemporal behavior.
Rheological aging and rejuvenation in solid friction contacts.
TL;DR: It is shown that low-velocity frictional properties of interfaces between a rough glassy polymer and smooth silanized glass exhibit the full phenomenology expected for confined quasi-2D soft glasses: they strengthen logarithmically when aging at rest, and weaken when sliding.
Magic angles and cross-hatching instability in hydrogel fracture
TL;DR: The full 2D analysis of roughness profiles of fracture surfaces resulting from quasistatic crack propagation in gelatin gels reveals an original behavior characterized by strong anisotropy with maximum roughness at V-independent symmetry-preserving angles and a subcritical instability leading to cross-hatched regime.
