Abstract

An efficient boundary element contact analysis based on an iterative and fully incremental loading technique is developed and implemented to solve non-linear frictional contact problems with conforming or non-conforming interfaces. This technique uses an updating process which allows the contact history to be followed from load-increment to load-increment. A traction extrapolation load scaling technique is used for each load increment to ensure that the unique combination of load, contact area and contact conditions is achieved for each po- tential contact node pair. In this paper, the problem of a tolerance-fit loaded pin in a cracked or uncracked lug is studied. The study shows that load transfer depends on the coefficien
