INITIAL STRESS DISTRIBUTION OF ORE IN CARGO HOLDS

The objective of this paper are to describe an effective method for simulating loading process of ore cargoes in a large ore carrier, and to determine the initial stress distribution of ore in a cargo hold. The experimental data on an actual ship by Hagiwara et al are compared with the results of the present method, and they show good agreement. Effects of loading processes and types of ore hold are investigated. From the comparison of these results, the authors come to the conclusion that the initial stress distribution of ore in an ore carrier in still water can be approximately determined by the plastic theory near the surface of ores and by the concept of earth pressure at rest for lower part of ore hold. The coefficient of earth pressure at rest can be obtained theoretically on the basis of the elastic constitutive equation proposed by the present authors.
