This paper is concerned with the rupture configurations in a full circular journal bearing. The rupture extent has large influences on the characteristics of a journal bearing, especially on its damping coefficients. It is necessary to estimate the rupture inception point more accurately. A numerical technique using the finite element method is proposed for two-dimensional analysis in the plane normal to the journal surface along its rotating direction. Oil cavity interface is treated as a free boundary, and the rupture configurations and the flow in the lubricating oil film are shown in the present paper.
