Simulation of Compressive ‘Cone-Shaped’ Ice Specimen Experiments using LS-DYNA®
A laboratory scale compressive cone-shaped ice experiments were performed, and a numerical simulation model using LS-DYNA was developed. Modified material properties were applied based on a crushable foam model (MAT 63) as the ice properties. To simulate a saw-tooth pattern which is commonly observed through experiments in ice, an additional function of failure criteria, which is maximum principal stress, was included. Results of the experimental and numerical simulation were compared and represented a good agreement. The proposed numerical simulation model was extended to a larger scale and verified.
