Numerical analysis of the stresses developed during the sliding of a cylinder over compact graphite iron

The finite element results were later compared with literature experimental pin on disc results with compact graphite iron discs. Good agreement was obtained when numerical and experimental analyses were compared. Both methods indicated that the contact stresses result in significant amounts of plastic deformation in regions close to the disc surface. Additionally, the finite element results allowed the observation of stress concentrations in the cast iron matrix, as a result of the presence of graphite flakes.
