Modelling of Ice-Structure Interactions by Using State-Based Peridynamics and Implementing in Finite Element Framework.

Description

The National Research Council of Canada – Ocean, Coastal and River Engineering (NRC-OCRE) has a requirement to conduct joint research and development on advanced peridynamic numerical analysis methods in collaboration with the Peridynamic Research Team at the University of Strathclyde. This research focuses on the development and application of peridynamic-based numerical techniques for modeling polycrystalline ice behavior and ice–structure interaction problems. The work will involve the creation of new computational routines to be implemented within commercial software platforms such as ANSYS, enabling complex simulation and analysis capabilities that have not been achieved elsewhere. The peridynamic method, originally developed in the early 2000s, is a highly specialized numerical approach used to analyze material deformation and fracture. The pre-identified supplier, Professor Oterkus and his team at the University of Strathclyde, are internationally recognized leaders in this field. Professor Oterkus is the author of a foundational textbook on peridynamics and has established the Peridynamic Centre at Strathclyde University, which is uniquely dedicated to advancing research in this domain. The proposed work will include: • Verification of peridynamic models through controlled experimental data; • Development of numerical modeling techniques for ice material behavior; • Integration of peridynamic routines into ANSYS for simulation of complex ice–structure interactions; • Validation of computational results through comparative analysis; • Monthly seminars and progress meetings to review outcomes and guide development; and • Preparation of a comprehensive research report summarizing findings at the conclusion of the second year. This initiative represents a unique and specialized technical service, as the Strathclyde Peridynamic Centre is currently the only research group worldwide with the expertise, infrastructure, and proven track record to perform this type of peridynamic numerical modeling and software integration.
