“…Liu et al [65] found that the crushable foam model lacks physical explanation and does not model cracks and damage produced during a typical ice-crushing interaction. In contrast, Han et al [66] found that in general the crushable foam, with a volumetric hardening function, is the most suitable ice material and typically used as an energy absorption structure. Nonetheless, even with the discrepancies between the ice material models, the general algorithm response up to its early termination has a similar response error when compared to the other benchmarking analyses for an impact on the frame, suggesting the algorithm as a whole has the potential to model more realistic loading scenarios.…”

Low- and non-ice-class ship-ice interactions are modelled with a shared-energy approach, which typically models the internal mechanics with nonlinear finite element methods. For applications like the preliminary design phase and quick operational assessments of the ship’s structural capabilities, a finite element shared-energy approach can be time consuming and information intensive, therefore, an analytical share-energy algorithm is proposed. The proposed algorithm applies the upper bound energy methodology by equating the external collision energy, determined with the Popov collision model (Popov, et al., 1967), to the sum of the internal ice and structural response energies. The distribution of the internal energy, between the ice and the structure, is determined by iterating through possible shared contact forces until the sum of the internal response energies equals the external energy introduced into the system. The ice-crushing energy is modelled with Daley’s (1999) energy based ice collision force models, and the internal structural strain energy is modelled through a combination of classical beam theory and design of experiments methodology. The proposed model is benchmarked against a finite element ice wedge-ship grillage structure interaction.

“…The determination of material properties and constants associated with ice deformation is uniquely challenging due to the complexity of the variables that influence this phenomenon. Numerous studies [3,5,9,19,20] have focused on the mechanical p r o p e r t i e s o f i c e , s u c h a s i t s c o n s t i t u t i v e r e l a tionships, fracture properties, and strain rate dependence, rather than the subtleties of its microstructure or thermal variations. Building on these findings, the present study incorporates the elastoplastic behavior, fracture characteristics, and strain rate sensitivity of ice.…”

“…Additionally, methods utilizing fluid-structure interaction to simulate ice-structure collisions have been explored [5], along with dynamic structural analyses focusing on the damage to both ice and structures [7,8]. Various constitutive equations and damage models for ice have been applied to predict collision force [3,9,10]. Despite the numerous approaches to ice collision force analysis discussed in the literature, this topic remains a subject of ongoing investigation.…”

“…For material constants that are difficult to measure or calculate directly, assumptions were made based on existing literature. Specifically, values from Tippmann [24], Kajaste-Rudnitski & Kujala [11], Zhang et al [12], Kim et al [4], and Han et al [9] were used to set the density and Poisson's ratio of ice to 900 kg/m³ and 0.3, respectively. Undetermined material constants for the CF and DP models were hypothetically varied and then incorporated into finite element analyses, ultimately yielding material constants consistent with experimental results.…”

This study explores the application of numerical analysis and material models to predict ice impact loads on ships and offshore structures operating in polar regions. An explicit finite element analysis (FEA) approach was employed to simulate an ice and steel plate collision experiment conducted in a cold chamber. The pressure and strain history during the ice collision were calculated and compared with the experimental results. Various material model configurations were applied to the FEA to account for the versatile behavior of ice—whether ductile or brittle—its elastic-plastic yield criteria, and its dynamic strain rate dependency. In addition to the standard linear elastic perfectly plastic and linear elastic-plastic relationships, this study incorporated the crushable foam and Drucker-Prager models, based on the specific ice yield criteria. Considering the ice’s strain rate dependency, collision simulations were conducted for each yield criteria model to compute the strain and reaction force of the plate specimens. By comparing the predicted pressures for each material model combination with the pressures from ice collision experiments, our study proposes material models that consider the yielding, damage, and behavioral characteristics of ice. Lastly, our study proposes a combination of ice material properties that can accurately predict collision force.
