A comparative analysis of the fluid-structure interaction method and the constant added mass method for ice-structure collisions
Song, Ming; Kim, Ekaterina; Amdahl, Jørgen; Ma, Jun; Huang, Yi (Journal article, 2016)The constant added mass (CAM) method and the fluid-structure interaction (FSI) method are widely used to simulate ship-ship and ship-ice collisions. In the CAM method, the hydrodynamic effect of the surrounding water is ... -
Estimation of ship bow-iceberg impact forces with consideration of the sliding effect
Song, Ming; Liu, Zhenhui; Amdahl, Jørgen (Journal article; Peer reviewed, 2018)A simplified method to estimate the impact force in ship bow-iceberg collisions is presented. The eccentricities of both iceberg and ship are included. The friction at the contact point is also included so that the sliding ... -
Fluid-structure-interaction analysis of an ice block-structure collision
Song, Ming; Kim, Ekaterina; Amdahl, Jørgen (Journal article; Peer reviewed, 2015)Due to climate change, production and transportation routes in Arctic regions are becoming more prevalent. When operating in Arctic waters, there is a significant risk of high energy encounters with smaller ice masses such ... -
Numerical Investigation of Fluid-Ice-Structure Interaction During Collision by an Arbitrary Lagrangian Eulerian Method
Song, Ming; Kim, Ekaterina; Amdahl, Jørgen; Greco, Marilena; Souli, M'Hamed (Chapter; Peer reviewed, 2016)When ice floes collide against marine structures, pronounced hydrodynamic loads are induced by the water-ice-structure interaction. With today’s highly competitive structural design market, it is nearly impossible to ignore ... -
Numerical Study of the Interaction between Level Ice and Wind Turbine Tower for Estimation of Ice Crushing Loads on Structure
Song, Ming; Shi, Wei; Ren, Zhengru; Zhou, Li (Journal article; Peer reviewed, 2019)In this paper, the interaction between level ice and wind turbine tower is simulated by the explicit nonlinear code LS-DYNA. The isotropic elasto-plastic material model is used for the level ice, in which ice crushing ... -
On a shifting pressure-area relationship for the accidental limit state analysis of abnormal ice actions
Kim, Ekaterina; Amdahl, Jørgen; Song, Ming (Chapter, 2017)The relationship between pressure and area is often used to describe various ice-structure interaction processes. With knowledge of the nominal contact area and the force, a continuous plot of average pressure versus ... -
On ice model validation and calibration strategies for damage as-sessment of structures subjected to impact actions
Kim, Ekaterina; Song, Ming; Amdahl, Jørgen (Chapter, 2016)The number of numerical ice models in structural design is growing, and classical Lagrangian finite element formulation is still dominant for numerical simulations. In design of ships and offshore structures, the numerical ... -
A Three-Dimensional Model for Strength Assessment of Type-C Independent Cargo Tank Structures
Song, Ming; Qin, Bin; Zhou, Li; Ren, Zhengru (Peer reviewed; Journal article, 2020)For the analysis of the arrangement and strength of Type-C independent cargo tank structures, the linear spring or rod elements are usually used to model supporting woods, in which one-dimensional and linear contact behaviors ...
