Purpose – Rotating machines play a strategic role in the process; it is the case of a gear unit of a cement mill. These machines are composed of tribo-pairs (bearings and gears, etc.) subjected to mechanical stress and ...
In this study, firstly we introduced general
mathematical concepts related to the geometrical form of
ellipse and ellipsoid. Secondly, the hardness was calculated
when we used an indenter having a geometrical shape of ...
In this theoretical study, we have chosen to use a body of an ellipsoidal geometric form as an
indenter, where we determined the mathematical expression of the static hardness as function of the
depth and the radii of ...
