Numerical Simulation of Ship Collision and Grounding Accident

The nonlinear finite-element digital simulation method plays an important role in the mechanical analysis of ship collision accident. Some practical use of this method in the analysis of ship-ship collision and ship-bridge collision was introduced, and the key techniques in applying it and calculation results were presented. Some results of benchmark study of numerical simulation to a model test of ship-side stringer collision were shown, which proves that the non-linear finite element method can produce a good simulation of collision procedure.
