2. Hertz pressure and deformation

This paragraph is based on ISO/TR 10567 and on the following references and .

The calculation of contact pressures and elastic deformations of bodies in contact (figure 5 ) is one of the most difficult subjects in the theory of elasticity. This chapter is limited to the calculation of Hertz pressure in ball or roller bearings under static loading, i.e. without sliding in the contact....
