This paper offers a new method to treat contacts in Eulerian Godunov formulations. The inadequacy of classic Eulerian formulations to describe contacts behavior is identified in the lack of degrees of freedom. This limitation is overcome by employing a set of state variables per material for the calculation of multi-material elements and faces. The extra state variables allow for the independent analysis of the materials present in the problem; materials interactions are characterized by introducing contact constraints in the formulation. The locality of the method limits the memory burden. Copyright © 2012 John Wiley & Sons, Ltd.
