Concrete-to-concrete shear friction behavior under cyclic loading [PDF]
The main objective of this paper was to study the concrete-to-concrete shear friction behavior under cyclic loading and different test rates. Eight dynamic push-pull tests were performed on concrete specimens with as-cast surface roughness type applying ...

Emergent friction in two-dimensional Frenkel-Kontorova models [PDF]
Simple models for friction are typically one-dimensional, but real interfaces are two-dimensional. We investigate the effects of the second dimension on static and dynamic friction by using the Frenkel-Kontorova (FK) model.

Dynamical friction in gravitational atoms [PDF]
AbstractDue to superradiant instabilities, clouds of ultralight bosons can spontaneously grow around rotating black holes, creating so-called “gravitational atoms”. In this work, we study their dynamical effects on binary systems. We first focus on open orbits, showing that the presence of a cloud can increase the cross section for the dynamical ...

The friction force is an important environmental factor that influences dynamic walking. While most of the related works simply assume static friction or Coulomb friction, we use the LuGre friction, which accounts for both static and dynamic effects, to ...
