Abstract. This paper advances a numerical method for analysis of elastic finite length line contact under any eccentricity. An existing algorithm solving the elastic contact problem with centric loading is generalized to the case of eccentric loading. An additional Newton Raphson outer loop is added to the classic conjugate gradient minimization in order to iterate the tilting angle, which enters the surface separation equation. Numerical simulations are performed on finite length line contact, and the effect of eccentricity upon pressure distribution and contact area is assessed.

Keywords: eccentric loading, numerical simulation, finite length line contact, end effect, pressure riser
