Summary

 
Object and purpose of research. This paper studies the model of dynamic ice failure that adequately describes local ice crushing specifics. The purpose of the study is to refine this model and introduce it to practical design of ice-going ships and icebreakers.
Subject matter and methods.This work relies on scientific & theoretical fundamentals of current requirements stated by various Class societies to ice strength and ice classes of ships, as well as on latest experimental data on physical & mechanical ice properties.
Main results. To introduce the dynamic ice failure model tailored for use in current RS ice classification, this work justifies the approaches to how the parameters of this ice model could be defined and quantified.
Conclusion. Based on theoretical studies and analytical analysis, this work refines dynamic ice failure model, justifying the approaches to definition and quantification of its parameters, enabling this model to be a theoretical basis for the regulatory ice load calculation formulae included to the Proposals on improvement of existing RS requirements to ice belts of ships and icebreakers. These new Proposals make it possible to reduce design ice load requirements without prejudice to ice strength, paving the way to reducing metal consumption of ice belt structure in future large icebreakers and ice-going ships.
