According to Greenwood and Tripp's model of asperity contact [10], assuming that the surface roughness of the piston ring and cylinder bore to be isotropic, the asperity contact pressure can be expressed as: Pasp=16215π(ηβσ)2E σβF2.5H (5) Where β is the radius of curvature of asperity peak, η is the asperity density, and É the composite elastic modulus of the surface materials.
