“…The in−plane and out−of−plane failures of a square ice sheet were investigated, and the results were compared with a splitting test by Vazic et al [10]. Another ice simulation with PD also involves polycrystalline S2 ice [11], ice−sloping/vertical structure interaction [12,13], and deicing [14]. Though a lot of works on ice mechanics were studied, these studies pay more attention to the ice mechanical model of idealized boundary conditions and the failure mechanism of an ice constitutive model rather than the practical application in the engineering field.…”

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.

“…Many updated mathematical models based on PD theory have been developed over the years: dual-horizon PD was proposed to solve the issue of spurious wave reflections when variable horizons are adopted (Ren et al, 2017); Dual-support SPH was developed in solid within the framework of variational principle (Ren et al, 2019); the PD differential operator provided a differential form for numerical analysis (Gao and Oterkus, 2020); as well as the combination of PD and FEM model (Madenci et al, 2018) and PD least squares minimization (Madenci et al, 2019). Recently, PD was applied to predict ice-structure interaction for a simple structure interaction with ice (Liu et al, 2017;Lu et al, 2018), which showed PD's potential to study ice fracture. Liu et al (2018) predicted the ice loads of a ship in rubble ice using the PD theory and Voronoi diagram.…”
