An unconstrained integral approximation of large sliding frictional contact between deformable solids

Abstract: A new integral approximation of frictional contact problems under large deformations is presented. Impenetrability, friction and the relevant complementarity conditions are expressed through a non-smooth equation, considered in the continuous setting. A weak formulation of this non-smooth complementarity equation is discretized through a standard Galerkin procedure, is linearized consistently and incorporated in a generalized Newton solution process. The resulting integral handling of contact and friction comp… Show more

“…2(b), is to define y as the closest intersection of the contact surface with the line passing through point x and having direction vector n x . The latter strategy, which can be referred to as ray-tracing, was studied in [29]. Gap functions corresponding to ray-tracing and projection with respect to a point x(X) are respectively defined by:…”
