Wet Particulate Materials - Flow or Fracture?
Grant number: DP150102788 | Funding period: 2015 - 2018
Most advanced materials are produced from starting materials in the form of fine particles. Powders, especially in ceramic engineering, are first processed wet into near-final shape. Improved understanding of the fracture of particle networks is critical in order to process nano-sized advanced ceramic materials for use in solar energy harvesting and extreme heat engine applications as well as minimising drying cracks in paints and coatings. The research aims to identify the fundamental link between particle network strength and structure and the fracture of wet powder bodies. The microscopic mechanisms that control the behaviour will be investigated with a particular focus on toughening mech..View full description
