Principal Knowledge Exchange Fellow

Advanced Forming Research Centre

Personal statement

Salah leads the Materials and Residual Stress team at the University of Strathclyde’s Advanced Forming Research Centre (AFRC), one of the UK’s seven High Value Manufacturing Catapult Centres. He is an expert in measurements, modelling and control of residual stress and in the mechanical and microstructural characterisations of materials. A key theme of his research is to utilise advanced materials characterisation techniques combined with in-situ mechanical loading experiments to better understand how microstructure affects the mechanical response of materials. The results from these experiments are then used to validate finite element simulations. Salah’s previous research had focused on meso-scale fracture  and the behaviour of materials under service loads in critical environments, using advanced photography techniques and electron microscopy to determine how microstructural features interacts with cracks. More recently, he has focused on developing novel techniques for measurements of manufacturing induced residual stresses to control dimensional tolerance and part’s non-conformance during manufacturing, while retaining desired microstructure. Salah joined the University of Strathclyde in 2010 where he is currently a Principal Materials Fellow leading the Materials and Residual Stress Team with over 20 staff including Research Fellows, Research Associates and Manufacturing Engineers.  He is also supervising  PhD and EngD students at Strathclyde Engineering Doctorate Centre funded by EPSRC.

Dr Rahimi, is a Fellow of The Institute of Materials, Minerals and Mining (IOM3) and he is registered as a Chartered Engineer (CEng).

Robotic Ultrasonic System for In-situ Residual Stress Measurement in Metal ‎Additive Manufacturing
Walker, Joseph (Post Grad Student) Javadi, Yashar (Principal Investigator) Heidari, Hadi (Co-investigator) Rahimi, Salaheddin (Co-investigator)
Residual Stress (RS) in engineering components yields unexpected and dangerous structural ‎failures, and thus ‎represents a significant challenge to quality assurance in both welding and metal ‎Additive Manufacturing ‎‎(AM) processes. As automation in welding and AM becomes increasingly ‎prevalent in the Industry 4.0 ‎manufacturing paradigm, so the importance of quantifying RS will ‎grow. In this PhD project, a novel robotic ‎ultrasonic approach to measuring such RS, in-situ, will be developed using the Phased Array Ultrasonic Testing ‎‎(PAUT) system, to automate the deployment of the ‎measurement in manufacturing applications. For the first ‎time, it will allow truly in-situ ‎measurements of RS to be undertaken at the elevated temperatures associated ‎with welding and ‎metal AM manufacture. The ambition is to use this in-situ measurement system for safety-‎critical and Industry 4.0 applications, through 5G wireless integration of the robotic system, where the ‎conventional manual and destructive methods of RS ‎measurement are not applicable for high throughput and ‎automated production lines.‎
