Abstract

Non-conform discretisation of the contact region applied to two-dimensional boundary element method A.Huesmann & G. Kuhn Universitdt Erlangen-Niirnberg, Egerlandstrafle 5, D-91058, Erlangen, Germany Introduction The most common way of applying frictional contact to a boundary ele- ment code is by a node-to-node strategy. This implies that the surfaces in contact have to be discretised by elements of equal length and equal type of boundary value approximation to ensure that the evolution of contact conditions is modelled most closely. Olukoko et al. [1] describe how to handle non-conforming contact discretisation. Compatibility and the law of friction are applied to the nodes of one of the bodies in contact (A) and traction identity is applied to the nodes of the other body (B). By this it is guaranteed that A does not penetrate B but not vice versa. Although nodal traction identity is applied equilibrium of contact force may be vio- lated. Blazques et al. [2] solve the problem of e
