Smart Materials and their Applications in Future Engineering
(Advert Reference on FindAPhD: RDF18-R/MCE/CHEN)
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. Many applications have been found in these materials, e.g. sensors, actuators, energy harvesters and cooling systems. The traditional smart materials such as piezoelectric materials usually have small linear coupling. As a result, they can only exhibit very small strain (~ 0.1%) when actuated by physical fields. In contrast, the recent advanced smart materials such as conventional/magnetic shape memory alloys/polymers have much larger strain (10% ~ 800%), more heat conversion, and much stronger couplings like ferro-elasticity, ferro-magnetism and ferro-electricity. These strong couplings usually induce the formations of multi-scale patterns in the materials, which lead to the global nonlinear behaviours.
The primary goal of this PhD project is to understand the relationship between the global nonlinear behaviours and the multi-scale patterns in smart materials by testing and modelling, to propose design guidelines for smart materials and structures, and to explore their applications in future engineering.
The work packages will include material characterisation, thermal and mechanical tests, theory studies and 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.
