Summary

 
The paper presents the results of experiments on the model ice failure modes conducted in the ice tank of the Krylov Shipbuilding Research Institute. The paper demonstrates that it is not valid to assume that the ice specimens are subject only to elastic failures, which is a common approach today. A detailed analysis of the breaking force versus time relationship has revealed that the plot has two sections with significantly different types of strain. One section is typical of the elastic behavior and the other is characteristic of non-linear behavior. It is shown that this type of failure mode is observed due to variation of critical parameters: loading rate, ice beam thickness and structure.
