O. (Omid) Hajizad
Omid received his bachelor degree in Mechanical Engineering from Sharif University of Technology in 2010. His bachelor thesis topic was “Numerical Simulation for Energy Absorption of Monolithic and Double-Layered Steel Plates under normal and inclined Impact”. Then he continued his master studies on Computational Mechanics in Technical University of Munich (TUM) and graduated in 2013. His master thesis research title was “Evaluation of Different Modelling Approaches for Process Induced Deformations (PID) due to Tool Part Interaction (TPI) during Composite Processing”.
Omid has research experience mostly on Computational Solid Mechanics both in university (Chair of Lightweight Structures, Chair of Metal Forming and Casting and Chair of Carbon Composites in TUM) and industry (DSM Company in Netherlands).
His main research interests include Multi-scale Theoretical and Computational Solid Mechanics, Computational Contact and Impact Mechanics and Mechanical Design Optimization.
Omid joined the Section of Road and Railway Engineering at Delft University of Technology in 2014.
Critical components of machines and structures often fail due to fatigue. Fatigue under rolling contact occurs in a wide range of engineering applications such as in wheels, rails, bearings and gears. The damage is detrimental to the economical and safe operation of the structures and the machines. Avoidance or improved control of damage development is desired. These may be achieved by improving the materials and by reducing the stresses and strains.
Omid’s research is mostly on the development of fundamental insights in the relations between mechanical loading, damage development, and microstructural features. Rolling Contact Fatigue (RCF) of rails will be the application case for the study.
His major concentration is on Computational Modelling of Material Microstructures, their evolution and the related damage under operational conditions.
