Background

Dr Ahmed is a lecturer in mechanical engineering within the school of Engineering and Physical Sciences (EPS) at Heriot-Watt University. Prior to this appointment in 1999, he held a post-doctorate research position at Cambridge University. Dr Ahmed completed his MSc and PhD from Brunel University.

Introduction

I am a team player within the micromechanics research group at Heriot-Watt University. My research interests include Tribo-mechanical modelling and evaluation of surface engineered materials, manufacturing processes, auxetic polymers, and residual stress. I am the principal investigator on various research grants, which have attracted funding from research council, industry, and miscellaneous other sources. Some of the outcomes from these projects can be seen from the list of publications.

I am also the director of studies for the MSc/diploma programme in Engineering Materials and Design within the school of EPS and also participated in the Scholar programme for undergraduate teaching. My research activities comprise of the following areas:

Nanotechnology and Surface Engineering

This research based upon nanocomposite and conventional overlay coatings aims to deliver novel coating solutions for high stress applications. This is achieved not only by controlling the process and process parameters, but also by appropriate design of the coating and substrate systems. Evaluations based upon the nano- and micro-mechanics of these coating substrate systems underpin the design of these coatings for a range of industrial applications. Recent work has included the development of novel coatings for orthopaedic implants (Patent – pending).

Mathematical and Numerical Modelling

This research activity complements research areas above by providing mathematical and numerical modelling approach for a range of engineering applications. Mathematical models have included areas such as structure property relationships, and tribology of manufacturing processes. Finite element modelling also forms part of this research activity.

Tribology of Manufacturing Process at Micro- and Nano-Scales

This activity involves tribological and mathematical modelling of processes such as cold rolling and strip drawing and aims to deliver efficient and environmental friendly solutions to the tribological design process.

Research on the Tribo-Mechanical Evaluations of Engineering Materials

This research activity involves the tribological evaluations of conventional and novel engineering materials to optimise the engineering design process. HIPed ceramics, Stellite alloys, steels, and auxetic polymers are some of the key areas which form part of this investigation.

Research in Non-Destructive Strain Measurement

Reliable modelling and fatigue life prediction of engineering components is influenced by the residual strain either due to the manufacturing process or service loading. This research aims to deliver numerical and mathematical models based upon experimental investigations.

Research Facilities

Apart from our collaborations with industrial and academic partners to share research facilities, some of the basic facilities include mechanical testing (hardness testers, tensile testing, charpy impact testing), microstructural/surface investigation tools (Microscopy, XRD, SEM, Interferometry, AFM), and various tribometers (rolling, sliding and abrasive wear). In addition specialised software for numerical modelling is also available.

Consultancy

We regularly undertake a range of consultancy work using our research expertise and facilities. Some of the recent clients included BBC radio Scotland, MTEM, Weatherford, BAC Corrosion Control Ltd, and IMES Ltd.

Studentships and Scholarships

Full or partial studentships or scholarships are generally available for UK and in some instances EU applicants. Overseas students with exceptional record are encouraged to apply for the Overseas Research Scholarship (ORS) scheme. Details of scholarships can be obtained from Mrs Janice Suttie (J.Suttie@hw.ac.uk) or by contacting Dr Ahmed (R.Ahmed@hw.ac.uk)
