The elastic deformation of the bearing liner is considered in determining the static and dynamic performance characteristics of the centrally loaded 120° arc bearing for eccentricity ratio up to 0.8 and mean Reynolds number up to 7500. Using the finite element method, the pressure distribution in the fluid film and the elastic deformation in the bearing shell are obtained by solving the Reynolds equation and the three-dimensional elasticity equations iteratively. The performance characteristics of the bearing are computed for different values of the deformation coefficient which is a measure of the flexibility of the bearing shell. In addition, some results are also reported for laminar and turbulent flow conditions treating viscosity as a function of pressure.
