Popis:	A heavy load analytic theory is developed which describes the way in which surface asperities cause variations in hydrodynamic pressure in an elastohydrodynamic conjunction. The theory is restricted to rigid sinusoidal asperities with a circumferential lay. It is shown that the magnitude of the pressure ripple increases with increasing asperity amplitude-film thickness ratio and decreases with decreasing wavelength, increasing load and increasing radius of curvature of the bodies. Pressure ripple magnitudes can vary from ∼106 Pa to infinite pressure spikes and it is suggested that elastic deformation of the asperities is to be expected at the higher values. Consideration is given to the way in which the theory may be applied to real surfaces.
