Web2 days ago · The numerical approaches, like FEM and semi-analytical methods (SAMs), have been involved to solve the non-hertzian contact problems. ... Whether it is a dry contact, lubricated contact or surface roughness is taken into account, the same discretization of the contact area must be done. The increased convergence speed of the SAM algorithm ... WebThis "fact" is built in to the Hertzian formula. Although it is obvious, and although for big rubber rollers the footprint at zero pressure is taken to be zero, in fact the Hertzian formula is wrong! At zero pressure the rubber naturally deforms to produce a finite contact width, a. That's because the surface energy forces are sufficient to ...
