A thermodynamic analytical model based on entropy production for predicting the grain size and yield strength of the joint formed by continuous drive friction welding

Journal of Materials Research and Technology, 2020
A self-consistent analytical model for predicting qualities of a joint welded by continuous drive friction welding (CDFW) was developed based on the Onsager-Ziegler maximum entropy production principle (OZ-MEPP), dislocation kinetics, and the CDFW ...

Influence of processing parameters on the tool and workpiece mechanical interaction during Friction Stir Welding [PDF]

, 2009
During Friction Stir Welding process, FSW, a tool / workpiece mechanical interaction is generated leading to forces and torques applied on the tool. These forces and torques are transmitted to the welding equipment impacting its technical requirements ...

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 ...

METHOD OF DIMENSIONALITY REDUCTION IN CONTACT MECHANICS AND FRICTION: A USER'S HANDBOOK. II. POWER-LAW GRADED MATERIALS

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.

The effect of groove texture patterns on piston-ring pack friction [PDF]

, 2012
A cylinder liner possesses fairly intricate surface requirements due to its complicated functions. It needs to provide adequate surface roughness to resist wear as well as to store and retain lubricants during high temperatures. The liner surface texture
