Background :

I am David Ajilore, a British Citizen originally from Nigeria in West-Africa. I obtained BEng honours in Mechanical Engineering from the University of Westminster, London that was followed by an MSc in Thermal Power, specialised in Rotating Machinery Engineering and Management from Cranfield University, Bedfordshire, UK.

I have over seven years in FE analytical roles and as mechanical design engineer for major companies including GEC Alsthom Power (Large steam turbine design), Converteam-GE Wind Power, Formula 1, and Automotive products Group.  Hence my current PhD project continues my career development in this sector of mechanical integrity of small components to very large machines.


PhD Project :

My PhD research mainly investigates the role(s) of delta in the creep embrittlement in IN718 superalloy by conducting elevated temperature slow strain-rates, creep and creep crack growth on the three different microstructures of IN 718. These different microstructures are delta-contained, delta-free and the delta plate-like will reveal also the strength, crack behaviour and characterisations aided by Direct Current Potential Drop (DCPD) and Digital Image Correlation (DIC) crack growth measurement tools.

This project in addition to above tests will use extensive computation (ABAQUS) and the load-line compliance have already been obtained for various crack sizes on a compact tension (CT) specimen. Computations will continue for creep for which the creep parameters have been obtained that correlated the steady-state creep history from test with other mechanical properties.
