The Local Pressure-Area Relation in Ship Impact with Ice.
The relation between pressure and area is used to describe various ice-ship interaction processes. Two types of pressure-area relations have been defined. One pressure-area relation describes the process of ship penetration into an ice feature. The other pressure-area relation describes the spatial...

| Summary: | The relation between pressure and area is used to describe various ice-ship interaction processes. Two types of pressure-area relations have been defined. One pressure-area relation describes the process of ship penetration into an ice feature. The other pressure-area relation describes the spatial distribution of pressure at an instant in time. The extensive local pressure data from the Louis S. St. Laurent and the Oden provide useful insights into the nature of pressure-area relations. The cases examined in this paper show that even though the two types of relations demonstrate similar trends of decreasing pressure with increasing area, they are quite different in nature. More examination of data in the context of the process pressure-relation is required before generalizations can be made. There is adequate data for describing the spatial distribution of local pressure as a function of area. NRC publication: Yes |
