Micro-plasticity of surface steps under adhesive contact: Part II – Multiple-dislocation mediated contact hardening
The study of the micro-plastic behavior of rough surface contact is the critical link towards a fundamental understanding of contact, friction, adhesion, and surface failures at small length scales. In the companion paper (Yu et al., J. Mech. Phys. Solids 55, 489-516, 2007), we have studied the onset of surface yielding due to single-dislocation nucleation from a stepped surface under adhesive ...
متن کاملElastoplastic contact of rough surfaces: a line contact model for boundary regime of lubrication
This paper introduces an improved friction model accounting for elastoplastic behavior of interacting asperities along contiguous rough surfaces for a line contact solution. It is based on Greenwood and Tripp’s original boundary friction model and specifically tailored for a boundary regime of lubrication. The numerical solution of Reynolds’ equation is achieved by implementing Elrod’s cavitati...
متن کاملThe Investigation of the Effect of Contact Frequency upon Thermal Contact Conductance
Thermal Contact Conductance (TCC) between an exhaust valve and its seat is one of the important parameters to be estimated in an internal combustion engine. An experimental study presented here to acquire temperature in some interior points to be used as inputs to an inverse analysis. An actual exhaust valve and its seat are utilized in a designed and constructed setup. Conjugate Gradient Metho...

متن کاملSelf-similarity of contact line depinning from textured surfaces
The mobility of drops on surfaces is important in many biological and industrial processes, but the phenomena governing their adhesion, which is dictated by the morphology of the three-phase contact line, remain unclear. Here we describe a technique for measuring the dynamic behaviour of the three-phase contact line at micron length scales using environmental scanning electron microscopy. We ex...
