Abstract:
Micropitting and related surface fatigue mechanisms are influenced by the running-in behavior of contacting bodies subjected to rolling/sliding motion. The running-in of contacting surfaces results in significant change in many surface topography parameters, such as mean summit radius, the radius of individual summits, and standard deviation of summit height, which leads to contact pressure, real contact area, and plasticity index. In this work, running-in wear is simulated by developing a 3D numerical wear model. The simulation is performed on 3D rough surfaces having different skewness and kurtosis. It is shown that mean summit radius and radius of the individual summit are strongly influenced and significantly vary during wear process. It is found that a change in contact pressure and plasticity index can be related to a single topography parameter. The objective of this work is to show the topography parameters variation during running-in wear, which is hitherto not discussed elsewhere in detail. The variation with the number of cycles for roughness parameters determined from wear experiment and simulation are compared and a good match is found.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
