Abstract: This paper studies the effects of the ice velocity on the breaking length of level ice failing in downward bending against an immobile and rigid structure. A contact model which allows for local crushing was used as this is needed to be able to model the transient stage of the interaction. A critical ice velocity was identified which separates two failure regimes with very different dependencies of the breaking length of the ice velocity. In one regimes the ice fails during the transient stage of the interaction resulting in increasingly shorter breaking lengths as the ice velocity increases. In the other regime failure occurs in what can be considered to be a quasi-static stage and so there the breaking lengths vary around the static one.
