Profile

Dr Inna Gitman graduated from Perm State Technical University (Russia) in 2002; where she studied Mathematical Modelling of Systems and Processes. She was awarded her PhD in Civil Engineering from the Delft University of Technology (Netherlands) in 2006. The topic was representative volume and multi-scale modelling in quasi-brittle materials. After several postdoctoral jobs (on stochastic characterisation and reliability of saturated soils at the University of Manchester and finite elements for gradient elasticity and computational multi-scale modelling of mechanical stimulation of bone at the University of Sheffield) Dr Gitman joined the Department of Mechanical Engineering as a lecturer in 2009.

Research Areas

My main research interests are the modelling of solid and bio-materials. My work is mostly computational. The three main themes are Mechanics of Materials, Bio-Mechanics and Statistical & Stochastic Analysis.

Mechanics of Materials:

• Analysis of the materials behaviour within a multi-scale modelling framework using the homogenisation of Representative Volume Elements (in collaboration with Prof. Bert Sluys of Delft University of Technology, Netherlands, and Prof. Harm Askes of the University of Sheffield).
• Analysis and implementation of gradient-enriched continuum theories that can be used to capture a range of microstructure-driven phenomena such as wave dispersion, size effects and strain localisation (in collaboration with Prof. Elias Aifantis of Aristotle University of Thessaloniki, Greece, Prof. Harm Askes, and Dr Terry Bennett of the University of Sheffield).

Bio-Mechanics

• Analysis of the behaviour of the bone subjected to osteoporosis (in collaboration with Prof. Tim Skerry, Dr Eugene McCloskey and Dr Lang Yang).
• Modelling of bone as anisotropic continua (in collaboration with Prof. Harm Askes of the University of Sheffield, Dr Ellen Kuhl of the Stanford University, USA and Prof. Elias Aifantis of Aristotle University of Thessaloniki, Greece).

Statistical & Stochastic analysis

• Statistical analysis and stochastic characterisation of saturated soil (in collaboration with Prof. Michael A. Hicks of Delft University of Technology, Netherlands).
• Stochastic stability analysis (in collaboration with Prof. Mikhail B. Gitman of Perm State Technical University).

Research Grants

• 2009 Computational multi-scale modelling of mechanical stimulation of bone" funded by Wellcome Trust Value in People (principal investigator; with Dr Lang Yang and Prof. Harm Askes) Value: $68,301.
