The experimental flow stress curves of structural steels obtained from axisymmetric compression tests conducted under hot-working conditions very often include the frictional effects present at the tool/specimen interface. ...

The capability of a model to represent the complex friction behavior is particularly important for systems where friction has a major impact on motion precision. In this work a GMS-based model is proposed which would require ...

Due to the high pressures that are involved in tube hydroforming processes, high values of the friction forces are developed and, therefore, lubricants are usually employed to increase the formability of the workpiece. ...

We study the effect of viscoelastic dynamics on the frictional properties of a (mean-field) spring-block system pulled on a rough surface by an external drive. When the drive moves at constant velocity V, two dynamical ...

We study the Casimir friction phenomenon in a system consisting of two flat, infinite, and parallel graphene sheets, which are coupled to the vacuum electromagnetic (EM) field. Those couplings are implemented, in the ...

Friction is a complex phenomenon with negative effects on the precision of positioning systems. In this work, a single-state friction model for control purposes, aimed to simplify the implementation of control algorithms ...

In this paper, modelling and parameter identification of an inertia wheel pendulum benchmark is considered. This is an underactuated mechanical system useful for teaching and research. Attention is focused on deriving a ...

The objective of this study was to determine friction ratios that maximize energy dissipation on a seismic damper. The aforementioned friction damper basically consists of mass blocks that are able to slide on a flat ...

For controlling vibrations, a Semi-Active Friction Tendon (SAFT), which consists of a semi-active friction damper and an auxiliary spring that are linked to the structure by a cable, is studied experimentally, numerically ...

We develop the theory of quantum friction in two-dimensional topological materials. The quantum drag force on a metallic nanoparticle moving above such systems is sensitive to the nontrivial topology of their electronic ...
