Spleen stiffness: a predictive factor of dismal prognosis in liver ...
WebBased on Eq. ~4!, the contact stiffness for smooth solids can readily be calculated and typical values for metallic surfaces are of the order of 10 GN/m, which are unrealistically high. As de-scribed in the next section, the presence of surface roughness decreases the values of the contact stiffness by several orders of magnitude. 2.2.2 Rough ... Web1 de abr. de 2024 · The normal tire stiffness factor is the first derivative of the normal wheel load with respect to the normal tire deflection . The slip is defined according to the deformation theory as the ratio of tire lateral deformation to half the contact spot length, and the longitudinal wheel slip is also taken into account [ 1 , 6 , 8 , 19 , 21 , 22 , 25 ]. irs downtown indianapolis
