DESCRIPTION:Ice action on ships occurs when a ship collides with an ice fe
 ature &ndash\; be that level ice\, ice floes or iceberg s. The total force
  acting on the ship depends on the motion of the ice feature and ship. The
  motion includes rigid body motions (in 6 DoF for ship and ice)\, elastic 
 deformations of ship and ice and irreversible deformations (ice crushing a
 nd ship hull plastic deformation). In principle all these should be taken 
 into account in modeling the collision and the total force. Several simpli
 fications have been made and the lecture describes some of the modeling th
 at has been carried out in order to determine the total collision force. A
 n interaction exists also for local ice loading i.e. ice pressure. In this
  case the local deformation of the ship hull interacts with the deformatio
 n of ice. One example of this is given also in the lecture.
