Bearing Stress
A bearing stress is the normal stress on the contact surfaces of mating surfaces. It is averaged over the total contact area and is calculated using the classical equation for normal stress (S = F/A). An example of a bearing stress is the contact stress between the dogs and the loading shoulder of a dog coupling.
