Profile
Dr Hassan Ghadbeigi graduated in Manufacturing Engineering in Iran and joined the University of Sheffield in 2006. He obtained his PhD in 2010 from the University of Sheffield in the field of mechanics of cutting operation. He was a member of IMMPETUS as Research Assistant (2006-2010) and was involved in projects on modelling and characterisation of material deformation during thermo-mechanical processing. Hassan was working on quantification of local deformation and damage in Advanced High Strength Steels as Post-Doctorate Research Associate (2010-2012). The project was in collaboration with Tata Steel Europe and M2i, the Netherlands. Dr Ghadbeigi has become a member of academic staff in 2012.
Areas of Research
Dr Ghadbeigi’s research activities are in the field of machining, mechanics of deformation in manufacturing operations, experimental mechanics, mechanics of materials and surface treatments applied to metallic alloys as well as damage, fatigue and fracture. Shot-peening and surface treatments are used to improve fatigue life of mechanical components. Modelling techniques including implicit/explicit and Arbitrary Lagrangian Eulerian (ALE) finite element are used to simulate manufacturing operations (machining and thermo-mechanical processes) and damage/fracture process in metallic and non-metallic materials. Multi-scale mechanical testing is carried out combined with full-field optical and Scanning Electron Microscopy based Digital Image Correlation to characterize micro/macro deformation and damage mechanisms.
Current research activities
- Damage and fracture of spot welds in automotive steels
- Local damage and deformation analysis of multi-phase high strength automotive steels (Dual phase, TRIP and Complex phase)
- Modelling of chip formation during milling operation of aerospace materials
