This paper presents results of theoretical and experimental research explaining the
retrograde final-stage rolling of a disk under certain relations between its mass and …

The general motion of a sphere in a mechanism in contact with a rigid planar surface under
rolling, sliding and spinning friction is studied in the context of non-smooth contact dynamics …

In recent years, there has been a growing recognition that the rocking motion of structures,
especially cylindrical ones, should be evaluated with three‐dimensional (3D) models …

A thermal-mechanical coupling model describing energy dissipation of cyclotetramethylene-
tetranitramine (HMX) explosive particles subjected to drop-weight impact is developed …

We report on the unexpected precessional motion that occurs when a small, rigid ring is
rotated on a vertical smooth rod. Using high-speed imaging, two distinct regimes of motion …

Coulomb friction model with unilateral contact is a basic, but reliable, model to represent the
resistance to sliding between solid bodies. It is nowadays well-known that this model can be …

We report an unexpected reverse spiral turn in the final stage of the motion of rolling rings. It
is well known that spinning disks rotate in the same direction of their initial spin until they …

A lack of accurate description of the meshing characteristics and the corresponding frictional
mechanism of the harmonic drive gear has limited progress toward modeling the hysteresis …

The concept of a trend toward a singularity has been discussed now for over 50 years. While
many focus on the accelerated rate of technology change, other indicators also seem to be …

A spinning disk on a rough horizontal surface is a familiar example presented in the
textbooks of classical mechanics. Recent studies have revealed that this simple system …
