Friction is an important source of dissipation in dynamical systems. Properly considering it in the numerical model is fundamental to obtain stable and representative responses in structures and ...

Physicists have wrestled with friction for centuries. Leonardo da Vinci sketched its rules in 1493, and two hundred years later Charles-Augustin de Coulomb showed that resistance has less to do with ...

Robots acting as macroscale analogs of active nanoparticles stop moving through friction alone, revealing a self-sustained cooling effect without external input. (Nanowerk News) How can a horde of ...

How can a horde of active robots be automatically brought to a standstill? By arresting their dynamics in a self-sustained way. This phenomenon was discovered by physicists at Heinrich Heine ...

Abstract: Simulating frictional contact between objects with complex geometry is important for 6-DoF haptic rendering applications. For example, friction determines whether components can be navigated ...

ABSTRACT: This study investigates the influence of strut height on the shimmy stability of aircraft nose landing gear through both theoretical modeling and experimental validation. A nonlinear dynamic ...

Researchers have made groundbreaking discoveries in superlubricity, demonstrating how this state of minimal friction could revolutionize energy efficiency in mechanical systems. Their work reveals ...
