Archard Wear Equation

This short video explains the definition of Archard wear equation, which is typically used for calculation of the sliding wear experimentally and numerically in tribology. Volumetric wear, linear wear, linear wear rate.

How hardness is taken in MPa? Hardness is normally dimensionless number, it is on a scale like brinell or vicker etc. From where can we take value of K? Thanks

[@Ephidlectures]

Thanks for your question, the hardness is not unitless. The SI unit of hardness is Pa or MPa. Here it has been taken MPa or N/mm2 to have the other length dimensions in mm. By the way, the value of K can be achieved experimentally.

[@sharjeelahmed6002]

@@Ephidlectures Thanks for reply. Actually while performing calaculations, we do not have experimental setup. Are there any standard tables from where we can take approximate values of k for general material pairs. Like SS and MS etc.

5:20 why convert to mm?

[@Ephidlectures]

Because the hardness has been put in MPa or N/mm^2. So the units should be compatible. Also, we would like to get the wear volume in mm^3.
