• Analytical and numerical analysis of iceberg collisions with ship structures 

      Liu, Zhenhui (Doktoravhandlinger ved NTNU, 1503-8181; 2011:235, Doctoral thesis, 2011)
      The scope of the present Ph.D. thesis was to investigate the mechanics of collisions between icebergs and ship structures. Large reservoirs of oil and gas and new sailing routes in the Arctic area are two large motivations ...
    • Discussion of assumptions behind the external dynamic models in ship collisions and groundings 

      Yu, Zhaolong; Liu, Zhenhui; Amdahl, Jørgen (Journal article; Peer reviewed, 2019)
      In the past decades, a prevailing way for the assessment of responses in ship collisions and groundings has been to decouple the problem into two parts: external dynamics and internal mechanics. The external dynamics deals ...
    • 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 ...
    • On multi-planar impact mechanics in ship collisions 

      Liu, Zhenhui; Amdahl, Jørgen (Peer reviewed; Journal article, 2019)
      This paper presents a new solution for ship impact dynamics in multi-planar space. A collision matrix is presented. It is derived on the basis of impact dynamics for rigid bodies. Effective mass factors are introduced ...
