Personal profile

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 24 staffs including Research Fellows, Research Associates and Manufacturing Engineers.  He is also supervising  PhD and EngD students at Strathclyde Engineering Doctorate Centre funded by EPSRC.

 

The Advanced Forming Research Centre

The forming and forging centre of the High Value Manufacturing Catapult, the Advanced Forming Research Centre (AFRC) at the University of Strathclyde, addresses key manufacturing process challenges in the forming and forging field. These challenges include optimising forging and forming processes to reduce energy and materials use, and also enhance the material properties of the components. The AFRC works with its industrial members on a core research programme which has a key theme on the effects of forging and forming process parameters such as heat treatment and quenching on residual stress evolution and microstructure character distribution within components. The subject of residual stress is a major area of expertise within the AFRC materials department, with a team of scientists using state of the art equipment (including X-Ray Diffraction, Electronic Speckle Pattern Interferometry, digital image correlation (DIC), and hole drilling techniques) to measure and characterise residual stress magnitude and distribution in a variety of components and materials. The materials department also hosts extensive materials characterisation capabilities, including 2 electron microscopes (providing capabilities for high temperature in-situ thermos-mechanical examinations up to 1200°C, along with chemical and crystallographic analyses), optical microscopy, and a wide range of mechanical testing equipment including the capability to test at industry relevant temperatures (sub-zero to 1100C) and strain rates (i.e. 10-6 – 500 s-1). Industry scale trials are a key capability of the AFRC, and are achieved through the use of production scale forming and forging equipment (including, for example, a 2100T screw press, 500T hydraulic press, 1200T Superplastic Forming press) within the centre, and supported by a team of manufacturing engineers, researchers, and technicians.

The residual stress team will make use of our extensive residual stress laboratory facilities and expert team to carry out the measurement of residual stresses in the forged composite components. Depending upon the samples and manufacturing processes used, the AFRC would make use of a combination of different residual stress measurement techniques to provide the most appropriate representation of the magnitude and distribution of residual stresses in the forged components.
