Abstract

The internal stress distribution in elastohydrodynamic lubrication of rolling/sliding line contact was obtained. The technique involves the full EHD solution and the use of Lagrangian quadrature to obtain the internal stress distributions in the x, y, z-directions and the shear stress distribution as a function of the normal pressure and the friction force. The principal stresses and the maximum shear stress were calculated for dimensionless loads ranging from (2.0452 × 10−5 ) to (1.3 × 10−4 ) and dimensionless velocity of 10−10 to 10−11 for slip ratios ranging from 0 to pure sliding condition.
