Structural Analysis of the Collapsing Bow of a Striking Ship

摘要

A mathematical model and structural dynamic computer program have been developed for the analysis of the collapsing bow of a striking ship. The model can be used to predict the collision impact force and the extent of damage of the striking ship bow in both perpendicular and oblique collision. The ice breaker POLAR STAR was used as an example for testing the computer program for an oblique collision angle. The companion report has been released under the title 'Formulas and Procedures for Estimating Collapse Loads of Ship Structural Members,' Report No. MA-RD-940-81066.
