Research Interests & Achievements
Professor Mark Hoffman's work covers a wide range of topics in the areas of fracture, fatigue and wear of coatings, ceramic-metal composites, polymers and steels. Specific contributions in these fields include:
- Identification of the mechanism for cyclic fatigue crack growth in partially stabilised zirconia
- Explanation and modelling of the toughening process in ductile phase reinforced CMCs
- Development of a means of assessing the fracture and fatigue characteristics of polyvinylchloride pipes following the addition of toughening modifiers (cited in ISO11673.2)
- Clarification of the effects of ductile-phase upon crack propagation in functionally graded materials under fatigue and monotonic loading
- Identification and modelling of the hysteretic behaviour of ductile phase reinforced CMCs during thermal cycling,
- Development of a framework for non-explicit computational materials modelling and its integration with finite element modelling
- Development of understanding of subsurface deformation processes during wear and contact, including cyclic, of hard coatings on metallic substrates
- Characterisation of fatigue behaviour of functional ceramics under mechanical loading.
Since 1999, Professor Mark Hoffman has received continuous funding from the Australian Research Council (ARC) including, as 1st Chief Investigator:
- 6 ARC Discovery/Large Grants
- 1 ARC International Researcher Exchange Grant
- 2 ARC Linkage Infrastructure Grants
- 1 ARC Linkage Project Grant
Total research funding received in last 6 years is in excess of $4m.
