Numerical study of an ice body impacting a cantilever plate based on an OSBPD-FEM hybrid method

Ice impacts frequently appear in many fields of engineering, such as aviation, marine, and civil. Structures tend to respond with a large amplitude displacement when the impact load is relatively high, resulting in significant structural safety threats. An ice-structure interaction model was established based on an OSBPD (Ordinary State-Based Peridynamics) and NLFEM (Nonlinear Finite Element method) hybrid method. Unlike other coupling methods that primarily focus on a single computational domain, the hybrid method employs Peridynamics and FEM to solve different computational domains separately, leveraging the respective advantages of these two computational methods. Additionally, an efficient technique was put forward to manage contact forces between the FEM domain and the Peridynamics domain, achieving satisfactory simulation results. An experimental setup of an ice sphere impacting a cantilever plate was established, and the numerical models were verified by comparing the results of...
