Personal profile


I am Dr Obeid Obeid, Lecturer in Mechanical & Aircraft Engineering at the University of the West of Scotland (UWS). I am holding a PhD certificate in Mechanical Engineering from Brunel University and MSc certificate in Advanced Manufacturing Systems from Brunel University. I am Chartered Engineer and Member of the Institution of Mechanical Engineers (CEng MIMechE). I have achieved the status of Fellow of the Higher Education Academy (FHEA) in recognition of teaching and learning skills within the UK Professional Standards Framework. 

In the meantime, I am teaching in Mechanical & Aircraft Engineering at the University of the West of Scotland as a lecturer for “Analysis & Simulation”, “Design Analysis-Dynamics”, “Design & Applications”, “Applied Engineering Science”, “Engineering Mechanics”, “Group Project”, and “Applied Finite Element Analysis” modules for MSc and undergraduate students.

Main PhD research interests are the mechanical behaviour of lined pipelines under critical problems. The research comprehensively covers the effect of residual stresses produced from welding and dynamic impact on the lined pipe experimentally and numerically. Currently, I am working on modelling 3D Additive Manufacturinf for multi-metal powders using Selective Laser Melting SLM. Besides that, I have a good experience in Oil & Gas industry particulary in Pressure Vessel, Pipelines and Boiler Inspection.

I have several published journal papers (high quality journals, Elsevier and Springer) and still continuous. I have reviewed several papers in Elsevier. I am looking for funding from industry for further progress in the PhD research and 3D Printing Additive Manufacturing.

Current research activities

Currently, I am working on modelling 3D Additive manufacturing for multi-metal powders using selective laser melting SLM. I am using ANSYS code associated with APDL subroutines, mathematical computation, to simulate the laser beam movement over the powder layers. The purpose of this project is to find the temperature evolution and residual stresses.

In my PhD studies, I have studied two critical problems regarding lined pipes (stainless steel pipe inside carbon steel pipe): welding and dynamic impact. The production of lined pipes depends on heating the carbon steel pipe up to 500°C and cooling the stainless steel pipe down to -200°C. The manufacturing process of lined pipes is known as tight fit pipe (TFP). The special welding process used in lined pipes typically consists of the overlay welding (inner welding) of the liner (stainless steel pipe) with the carbon steel pipe for each segment and the girth welding (outer welding) of the two segments. This case could be extended to different several weldings with different base materials. The second problem which has been investigated in my research is the dynamic impact problem. It is a crucial one for lined pipes because of the reduction in the thickness of the outer pipe ensured by the internal protection from corrosion given by a thinner liner. This case could also be expanded to include dynamic impact for multi-layer pipe. To simulate both processes using the ABAQUS code associated with FORTRAN subroutines as well, nonlinear and mechanical finite-element (FE) analyses have been conducted. Furthermore, a significant number of experiments for both cases had been executed using thermocouples, strain gauges and LabVIEW software to analyse experimental results in National Instruments Data Acquisition (NI DAQ). Residual stress gauges were also used in my project to find the areas with higher plasticity which in turn led to possible locations of material failure under thermal welding and impact fatigue. To double check the experimental results, X-Ray Diffraction had been used. Furthermore, Scanning Electron Microscope (SEM) had been used to show the structure of welding and impact cross section. Also, Non-Destructive Tests (NDT) had been used to detect surface cracks after welding and impact process.

Besides that, I have an interest in studying the welded steel structure segments under vibration to study the strength, cark and fatigue of the connected segments.  

Area of academic expertise - outline

Computational Design: using ANSYS & ABAQUS codes associated with APDL and FORTRAN codes, repectively, to develop complex finite element analysis FEA models.

Target collaborative organisations

Some academic institutions are in race to develop the utilizing for multi-metal powders such as TWI, NASA and other prestigious universities. I have contacts with some of these institutions to have a consortium and to submit one collaborative EPSRC application. In this case, the opportunity to get the fund will be higher.
