A STUDY ON THE STRUCTURAL STRENGTH OF SHIPS IN COLLISION (2ND REPORT)

The first report is concerned with the analyses of the results obtained in various series of static collapsing tests of ship side models compressed by rigid bow models. Important are as follows: (a) There are two typical mechanisms of energy absorption in case of collapse of ship side models. They are buckling-type and encroaching-type. (b) Formulas to relate load with penetration and to relate absorbed energy with penetration are presented for two mechanisms respectively. This second report is concerned with dynamic collision tests carried out on two typical ship side models, namely buckling-type models and encroaching-type models. The main purpose of the experiment is to make clear the effect of collision speed on the absorbed energy. The automobile collision test apparatus was used. The car with rigid bow model on the leading edge was crashed on the ship models with were fixed on the wall through load measuring pickups. The analyses of the collision test results show that the absorbed energy of an actual ship at the time of collision is able to be estimated rather well based on the results of static analyses, in considering the fact that strength of the material becomes apparently higher when the strain rate becomes higher.
