Is internal friction friction?
Geophysical Research Letters, 1996 Mogi [1974] proposed a simple model of the incipient rupture surface to explain the Coulomb failure criterion. We show here that this model can plausibly be extended to explain the Mohr failure criterion. In Mogi's model the incipient rupture surface immediately before fracture consists of areas across which material integrity is maintained (intact ...

Multi-physics simulation of friction stir welding process [PDF]
, 2009 Purpose: The Friction Stir Welding (FSW) process comprises of several highly coupled (and non-linear) physical phenomena: large plastic deformation, material flow transportation, mechanical stirring of the tool, tool-workpiece surface interaction ...

Facta Universitatis. Series: Mechanical Engineering, 2016 Until recently, the only way of solving contact problems was to applythree-dimensional contact theories. However, this presupposes higher mathematical and numerical knowledge, which usually only research groups possess.

Structural friction anisotropy on the nanometer scale [PDF]
, 2013 The ability to understand and control friction on an atomic scale is becoming increasingly important, not only considering the increasingly small scale of mechanical systems that are being developed, but also in respect of furthering the fundamental ...

Identification and model-based compensation of Striebeck friction [PDF]
, 2006 The paper deals with the measurement, identification and compensation of low velocity friction in positioning systems. The introduced algorithms are based on a linearized friction model, which can easily be introduced in tracking control algorithms ...
