Trouwborst, W. TNO Bouw en Ondergrond Publication year 2008 Abstract Three-dimensional simulations were done of a heavy underwater shock trial on a floating cylinder, which was executed in 1996. The analyses were done using the so-called Simplified Interaction Tool, an approximate interaction method developed by TNO as an add-on to LS-DYNA. The analysis was continued beyond cavitation closure into the whipping stage. The simulation results were compared against experimental results from the shock trial as well as previous two-dimensional simulation results using a hydrocode. While the 2D hydrocode analysis provides a principally better simulation of the fluidstructure interaction, the 3D analysis has the capability of modelling the 3D structural details correctly. Comparison against the experimental results shows that the new 3D analysis provides better results.
