SIMPLIFIED THEORY FOR NON-HERTZIAN CONTACT

In the paper a simplified theory is proposed both for contact formation and for frictional rolling, in which the contact area is not known in advance, and, indeed, may be non-Hertzian. The program first determines the contact area on the basis of the given total normal force, and then applies the FASTSIM algorithm in the contact area on the basis of the given creepages and the spin, to find the total tangential force.
