Development of a semiimplicit contact methodology for finite volume stress solvers Academic Article uri icon

abstract

  • AbstractThe past decades have seen numerous efforts to apply the finite volume methodology to solid mechanics problems. However, only limited work has been done by the finite volume community toward the simulation of mechanical contact. In this article, we present a novel semiimplicit methodology for the solution of static forceloading contact problems with cellcentered finite volume codes. Starting from the similarities with multimaterial problems, we derive an implicit discretization scheme for the normal contact stress with a straightforward inclusion of frictional forces and correction vectors for nonorthogonal boundaries. With the introduction of a sigmoid blending function interpolating between contact stresses and gap pressure, the proposed approach is extended to cases with partially closed gap. The contact procedure is designed around an arbitrary mesh mapping algorithm to allow for nonconformal meshes at the contact interface between the two bodies. Finally, we verify the contact methodology against five benchmarks cases.
