| Abstract: | By adopting nonlinear finite element technique,the paper discusses the model simulating the parameteres of fallen objects colliding on offshore platform,and studies the effects of the collision forces with different velocities and places,the structural damage and the energy absorption capacity.The simulation is carried out by MSC/Dytran,a three-dimensional analysis code for analyzing the dynamic,nonlinear behavior of the structure. |
