Abstract: An improved DMT adhesion model in conjunction with an elastic-plastic contact model is used to study adhesion of contacting metallic rough surfaces. The effects of surface roughness and surface ...

Abstract: The friction force required to shear interface bonds of contacting metallic rough surfaces is calculated, taking into account the prestress condition of contacting asperities. The surfaces are ...

Abstract: An elastic-plastic asperity model for analyzing the contact of rough surfaces is presented. The model is based on volume conservation of an asperity control volume during plastic deformation. ...

Abstract: Mass transport in an air-breathing cathode of a proton exchange membrane (PEM) fuel cell was investigated numerically. The porous cathode in contact with a perforated current collector breathes ...
