Research Project Title:
Plasticity induced magnetisation losses in energy conversion processes

Research Project Summary:
Cutting of metallic sheets causes defects, which enhance magnetisation hysteresis and energy conversion losses. The structure defect in crystal can interact with the magnetic domain boundary. The molecular dynamics (MD) simulation can model the microstructure of the defect cores predictively but the magnetism and magnetic domain boundaries are rarely modelled together in MD simulation.

In this project, we aim to identify the mechanisms of energy conversion loses to develop mechanism-based materials design approach to increase conversion efficiency. This aim requires to develop and implement a MD simulation which can combine the atomic position and magnetization.

Student Profile:
I completed my bachelor’s degree in mechanical engineering at Nanjing Tech University in 2017, following with the Master of Engineering (Mechanical) at the University of Melbourne in 2020. I did some projects about material simulation during the study in UoM. It is excited to implement new material design (especially the atomic simulation) and there are many things to do in this field.

I decided to do a research degree which can offer me a chance to explore this amazing material simulation field. I browsed this joint PhD project and felt it is a good opportunity for my following research study. I will work for the simulation of magnetic domain boundary interacted with the dislocations in Iron.

Project Duration: 3.5 years
