Abstract
The pressure in the lubricant film of a long hydrodynamic journal bearing is non-axisymmetric in nature. Therefore, Lamé's equations are not valid to calculate the stresses and deformation of the bearing. In this paper, a closed-form solution has been obtained to calculate the stresses and deformation of the bearing by means of Airy's stress function approach. The bearing has been considered as a thick cylinder under plane strain loading. The pressure distribution on the bearing has been represented by Fourier series whose coefficients have been calculated by Simpson's composite formula for numerical integration. The variation of hoop stress and deformation of the inner surface of the bearing has been plotted.
