Two-State GMS-Based Friction Model for Precise Control Applications
(Springer, 2016-05)
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 ...
A simplified model for friction compensation in precise feed drives
(Inderscience Enterprises, 2018-11)
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 ...
A non-linear Cosserat rod model for drill-string dynamics in arbitrary borehole geometries with contact and friction
(Pergamon-Elsevier Science Ltd, 2019-07)
A model for drill-string dynamics in arbitrary borehole geometries based on the Cosserat rods theory is presented. The objective of this work is to exploit the capabilities of the Cosserat rods to capture the full range ...
A literature survey on electrical-current-assisted friction stir welding
(Multidisciplinary Digital Publishing Institute (MDPI)Switzerland, 2023)
Finite strain model for contact interface in forming processes
(Wiley, 2006-12)
A phenomenological rate and state-variable friction law for the continuous sliding under lubricated and dry conditions, asit occurs in metal forming processes, is presented in this paper. The contact model is developed ...
Thermal corrections to quantum friction and decoherence: A closed-time-path approach to atom-surface interaction
(American Physical Society, 2019-05-15)
In this paper we study the dissipative effects and decoherence induced on a particle moving at constant speed in front of a dielectric plate in quantum vacuum, developing a closed-time-path (CTP) integral formulation in ...
Two-phase flow frictional pressure drop prediction in helical coiled tubes
(Pergamon-Elsevier Science Ltd, 2020-12)
Based on the construction of different experimental databases, the frictional pressure drop in helical tubes for single-phase and water-steam two-phase flow was analyzed empirically. The aim of the present study is to ...
A nonsmooth frictional contact formulation for multibody system dynamics
(John Wiley & Sons Ltd, 2020-08-07)
We present a new node-to-face frictional contact element for the simulation of the nonsmooth dynamics of systems composed of rigid and flexible bodies connected by kinematic joints. The equations of motion are integrated ...
Zener relaxation in manganites?
(Elsevier Science, 2006-10-11)
We conducted internal friction (IF) and elastic modulus measurements on several manganites in the temperature range 100-500 K. The La1-xCaxMnO3 series, with x=0, 0.1, 0.2, 0.33 and 1, was studied showing the magnetic phase ...
