| dc.description.abstract | Fuel cell technology have the potential of being a crucial element of reducing greenhouse gas emission from transport, mainly road traffic. The technology is still facing challenges that hinders it commercialization, mainly durability and cost. Yttria stabilized zirconia is one of the more studied electrolytes for use in solid-oxide fuel cells, because of its beneficial thermal and electrical properties.
In this thesis, mixed mode fracture behaviour of yttria stabilized zirconia in asymmetric four point bending is studied. Finite element analysis of the test specimen is performed to obtain geometric factors of fracture and prepare the experiment. Fracture load predictions are performed by average strain energy density criterion. | |
