Abstract:

The small ice model basin in China Ship Scientific Research Center (SIMB, CSSRC) employs columnar saline ice as a model ice in conducting experimental research on Arctic marine structures. It is essential to carry out foundational research to better understand the relationship between the microstructure of the model ice and its mechanical properties. This study utilizes the finite element method to simulate the model ice. The choice of material model is based on the failure mode and physical characteristics of the model ice. The internal porosity of the model ice is modeled using Java programming language by removing the elements. The spatial distribution function is determined based on pore distribution observations within the model ice. The procedure is called to ensure that the numerical model satisfies the requirements of the porosity characteristics, combined with the actual porosity obtained from the observation. Further, the simulation results are compared with the physical test results of the model ice to identify the numerical simulation parameters. This study provides a reliable method for the numerical simulation of model ice microstructure. It serves as a foundation for further research on the relationship between model ice microstructure and the mechanical properties of the model ice.
