Abstract
In the contact between a ball and a plate or between crossed cylindrical rods, the load bearing contact area, A b , is determined by the Hertz formula (8.02) provided the indentation be purely elastic. When the deformation becomes plastic, A b will correspond to Eq. (8.07), or particularly, when the specific depth of the indentation attains values above 0.02, A b will correspond to Eq. (8.06). In all these cases the contact surface is circular (elliptic between crossed rods of different diameters); and if it be entirely metallic and its linear dimensions are small compared with the dimensions of the contact members, the constriction resistance may be calculated according to § 4.
