Project Description

Smart materials are materials exhibiting multi-physics coupling behaviours. So they can be actuated by various physical fields, such as stress field, thermal field, electric field and magnetic field. Magnetic shape memory alloys appear as a new kind of smart materials exhibiting thermo-magneto-mechanical couplings. They can undergo large strain change (6% − 10%) due to the martensite reorientation or phase transformation induced by magnetic field, mechanical stress or temperature change. Compared with the traditional shape memory alloys, magnetic shape memory alloys have the advantage of high-frequency response, which makes them promising candidates for sensors and actuators in the future.

The primary goal of this project is to study the dynamic behaviours of magnetic shape memory alloys, understand the multi-physics (thermo-magneto-mechanical) coupling in the material, unveil the relationship between the macroscopic behaviours and the microstructure evolutions (e.g. magnetic domains, twin microstructures), and explore their potential applications in future robotic systems.

The work packages will include material characterisation, dynamic tests under multi-physics loadings, simulations and product design engineering. The project is expected to involve multi-disciplinary collaboration within Northumbria University in UK, as well as external partners in Europe and Asia.

Who this PhD would suit

This PhD project is well suited to motivated and hard-working applicants with a keen interest in smart materials and their applications. The suitable background of the applicants is: Mechanical Engineering or Material Science or Applied Physics.
The principal supervisor for this project is Xue Chen.
