“…The research on the performance of ram-type icebreaking icebreakers focuses on the ship's motions, the ice load on the bow, the penetration distance of the ship in the ice, and the ice destruction mode under different speeds and ice conditions. Research methods, as shown in Table 1, include full scale ship test methods [3][4][5][6][7][8][9], model test methods [10][11][12], and numerical simulation methods [13][14][15][16][17][18][19][20][21]. ships when they rammed thick multi-year ice floes.…”

When the icebreaker sails in the polar region, it adopts continuous and ramming icebreaking operations. When the ice condition exceeds the design working condition, it uses the ramming icebreaking method to advance. The nonlinear icebreaking process and complex ice conditions make it difficult to accurately predict the ice-strengthened ships’ ramming performance. This paper develops a scale-ratio brittle model of ice to simulate thick, level ice and predicts the ice penetration distance and bow load of an icebreaking research vessel (IRV) model at different speeds. The test results show that the penetration distance of the scoop-shaped bow IRV increases with the ramming speed and the average and extreme values of the contact load increase with the increase in the speed. The experimental results are a valid complement to the ice tank tests and do not cover all aspects of ship design. The main purpose is to develop a test program and performance prediction scheme for studying penetration distance and ice load during ram icebreaking.

“…In order to demonstrate the application of MPI parallelization in practical engineering cases, an icebreaker breaking level ice was studied in our previous work [25]. In this case, a complete icebreaker model was established to continuously break the level ice, with failure defined by critical stretch.…”

“…However, the update speed of Peridigm is far behind the progress of the current PD method. Zhang et al [25,26] investigated a continuous icebreaking process by proposed MPI parallel strategies and compared icebreaking differences between two typical icebreaker bows. It can be seen that the calculation efficiency of the PD method is increasing with the progress of research, but there is still a long way to go to reach the analysis of polar operations of structures under more complex conditions.…”

The peridynamic (PD) theory is based on nonlocal mechanics and employs particle discretization in its computational domain, making it advantageous for simulating cracks. Consequently, PD has been applied to simulate ice damage and ice–structure interaction under various conditions. However, the calculation efficiency of PD, similar to other meshless methods, is constrained by the number of particles and the inherent limitations of the method itself. These constraints hinder its potential for further development in the field of ice−structure interaction. This study aims to explore the computational efficiency of various methods that can be employed to improve the computational cost of PD in ice–structure interactions. Specifically, we analyze the computational efficiency of three different methods (the MPI parallelization, the updated link−list search method, and the particle−pair method) and their collaborative calculation efficiency to reduce simulation time. These methods are employed to calculate ice–ship interaction, and their coupled efficiency is studied. Furthermore, this study discusses the computation strategy to improve efficiency on using the PD method to calculate ice–structure interaction. The present work provides scholars who employ PD to calculate ice–structure interaction or ice damage with a referential discussion plan to achieve an efficient numerical computation process.
