IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

MODELLING ICE RIDGE PUNCH TESTS WITH COHESIVE 3D DISCRETE ELEMENT METHOD
Author : Arto Sorsimo, Jaakko Heinonen
In this paper we simulate a punch through test of partly consolidated ice ridge keel with three dimensional discrete element method. We model the contact forces between discrete ice blocks with Hertz-Mindlin contact model. For freeze bonds between the ice blocks we apply classical linear cohesion model with few modifications. In simulations we vary the parameters that are most relevant to maximum force on indenter and examine the causalities due to variation. In addition, the failure mechanisms in ice rubble are studied. We compare the simulation results to full-scale experimental results to confirm the feasibility of the model. The results show that the
