| Outline of Final Research Achievements |
Loss of life as well as disastrous environmental pollution may happen if ships is subjected to significant damage including ship collisions. Residual strength is defined as a strength that ships have sufficient strength even in damaged condition. It is important to have sufficient residual strength in order to preserve safety of life at sea as well as protection of environment. In the present study, in order to find out a mechanism of ship breaking in damaged condition a scale-model test as well as a series of state-of-the art numerical simulations were carried out and a research to develop advanced methods to estimate residual strength is carried out.
