| Abstract: | By means of nonlinear finite element simulation method,the dynamic process of the collisions between ship and bridge pier were calculated for four different ships with tonnages at different initial velocities respectively.A normal collision between ship and bridge pier were simulated.The damage of the ship and bridge pier were investigated in detail.Based on the numerical results,curves of collision penetration-velocity,curves of collision penetration-time and the stress process of the ship and bridge pier ... |
