S a dominant numerical tool in modelling continuous supplies both inside the linear and nonlinear array of deformation. It has some drawbacks when simulating macrocracks or fragmentation of your material [5,6]. On the other hand, the DEM quickly generates realistic macrocrack patterns and material Teflubenzuron MedChemExpress fragments provided its discontinuous nature [5,7]. The DEM is identified to much better simulate the propagation of an ice crack and fracture behavior mainly because the connection involving the particles can be modelled [7]. The DEM is broadly applied to ice modelling, ice breaking, and ice tructure interaction challenges [8].

Inside the DEM, every single person particle that contains properties in the ice may be described as a number of shapes for example a disk, a sphere, along with a polyhedron. The DEM could simulate several ice conditions, e.g., ice floes, level ices, and ice ridges by modeling the ice as individual particles or an assembly of particles [103]. For the ice floes, studies on an interaction involving ships or offshore structures plus the ice floes utilizing diskshaped particles that assumed unbreakable ice were carried out [148]. For the level ices, some research utilized bonds among particles to simulate contacts and cracks within the level ice [191]. The bond among two particles was broken when the maximum force acting around the bond exceeded a criterion, which could explain the crack and fracture phenomenon [22]. The ice breaking load in the DEM was extremely dependent around the mechanical properties of ice [235]. The bond Young’s modulus, flexural strength, and compressive strength have been related to parameters of speak to and bond models. It really is essential to define the parameters from the models that impact the mechanical properties of ice and to find out the connection amongst the parameters and also the mechanical properties of ice [23,26,27]. In the present study, the DEM was selected and applied to the threepoint bending test and also the uniaxial compressive test. For the simulations, the opensource discrete element method libraries have been used [13,28,29]. The partnership between the mechanical properties of your simulated ice and the parameters associated using the contact and bond models was investigated. The present paper is organized as follows. Section two describes numerical modeling including the governing equation for particle speak to and bond models, as well as the parameters for ice modeling. Section 3 presents the results and discussion for the parametric study. Lastly, in Section 4, concluding remarks are provided. 2. Numerical Modeling two.1.
