Computational Mechanics and Reliability Group

Postgraduate research

Our post-graduate research community benefit from our expertise in computational mechanics, wide network of industrial collaborators nationally and internationally, and our links to professional societies. Postgraduate students work within a vibrant research environment supervised by staff members and have the opportunity to present their work at international conferences.

Current PhD students:

Muhammad Umair Najeem, Microstructure Informed Modelling and AI for Reliability Predictions

Research Topic: The research project investigates how test data generated with state-of-the-art metrology and failure characterisation methods and systems can be deployed and used together with physics-of-failure and AI/Machine Learning modelling techniques to provide a microstructure-informed diagnostic and prognostic model-based methodology that can inform the reliability performance of microelectronic packaging and assembly designs. The research project is supported through the EU MSCA Doctoral Network programme MIRELAI (https://mirelai.eu/)

Expected Completion Date: November 2026.

Supervisory Team: Dr Stoyan Stoyanov, Dr Razia Sulthana, and Dr Stewart McCracken (industrial partner supervisor, MCS Ltd, Edinburgh)

Sheikh Hassan, Advanced Reliability Modelling for Electronic Components and Assemblies

Research Topic: The project has focus on the development of compact model methodologies and time-efficient reduced-order modelling methods for thermo-mechanical analysis using Krylov-subspace-based model order reduction (MOR) techniques applied and non-linear material models. The developed modelling methods enable simulating the behaviour of advanced semiconductor packages and predicting the associated stress-induced electronic material degradation and damage.

Expected Completion Date: November 2024.

Supervisory Team: Dr Pushparaj Rajaguru and Dr Stoyan Stoyanov

Aderonke Bella, Model Order Reduction Techniques for Electro-Thermal Analysis of Power Electronic Modules

Research Topic: Develop model order reduction (MOR) approach for electro-thermal finite element analysis of power electronic modules that is beyond current state-of-art in terms of computational efficiency and accuracy of the numerical modelling approximation.

Expected Completion Date: May 2024.

Supervisory Team: Dr Pushparaj Rajaguru and Dr Stoyan Stoyanov
