Dynamic Impact and Fragmentation
Dynamic impact and fragmentation are highly complex phenomena. Members of the Centre for Geotechnical Science and Engineering have been conducting world-class research on the topic applied to rockfall engineering.
Our team has developed sophisticated numerical models and advanced high-speed 3D tracking facilities over recent years to advance knowledge in this area.
Competitive advantage
- Unique impact and fragmentation testing facilities
- Access to customised CV-based 3D 6DoF tracking software
- Extensive expertise in developing advanced numerical models
- Expertise in conducting advanced full scale and small-scale material testing
- Outstanding interdisciplinary research team with extensive industry engagement, including Australian Academy of Science medallist and postdoctoral fellows
Successful applications of research
- Prediction of fragmentation probability from material properties
- Characterisation of the effect of fragment size on perforation energy of systems
Partners
- Road and Maritime Services
- Geobrugg AG
- Australian Coal Association Research Program
- Australian Research Council
Impact
- Optimisation of rockfall protection systems and impacted structures
- Better assessment of the amount of energy dissipated in fragmentation
- Prediction of kinetic energy of fragments for better protection
- Understanding of the failure mechanics and fragmentation process of impacting objects
Capabilities and facilities
