“…The material properties would be adopted as the crankshaft-bearing system in the marine engine. The crankshaft and steel back materials of the bearing are both steel materials, which could be set as the 2% linear hardening elastic-plastic material [26], while the coating (the commonly used babbitt metal SnSb11Cu6) could be set as the power-law hardening elastic-plastic materials [27]. The geometrical and material parameters are set as follows: The radius of the two asperities, R ; the coating thickness, t , of Asperity 2; the interaction, δ , between the two sliding asperities; the horizontal coordinate, w h , of Asperity 1; the Young’s modulus, E 1 , the yield strength, Y 1 , and the Poisson’s ratios, ν 1 , of Asperity 1; the Young’s modulus, E co , the yield strength, Y co , the hardening exponent, n , and the Poisson’s ratios, ν co , of the coating of Asperity 2; and the Young’s modulus, E su , the yield strength, Y su , and the Poisson’s ratios, ν su , of the substrate of Asperity 2.…”
