As shown in the attachment, the link (blue) is connected to two pins A and B (red). Force is applied by the pin A on the link along the x direction purely. A reaction force is expected at the corresponding point of contact between the pin B and the link I am told that the compressive stress produced around the contact region of the pin B and the link, is explained by the hertzian stress. I am unable to find any literature that might give me the method to calculate the contact stresses using hertzian stress criteria. 1. Is hertzian stress criteria the right way to approach this problem? 2. If yes, could someone please tell me how. Thank you.
