About

Dr. Essa is a lecturer in process modelling within the school of Mechanical Engineering. Following his PhD, Dr. Essa developed research projects in cooperation with Rolls-Royce, BAE systems and the MTC. During his PhD, Dr. Essa was the postgraduate finite element ABAQUS trainer at the University of Birmingham. Dr. Essa published more than eight journal papers, two conference papers and one text book based on his PhD research. He is awarded the Hufton Postgraduate award for his research achievements and has been nominated to the Birmingham International Employee of the Year award for his contribution to teaching.

Qualifications

Lecturer in Process Modelling

  • PhD in Finite Element Modelling of Incremental Sheet Forming, University of Birmingham, 2011
  • MSc in Tube Spinning processes, University of Alexandria, 2007
  • BSc in Manufacturing Engineering, University of Alexandria, 2003

Biography

Dr. Essa holds a PhD in Mechanical Engineering from the University of Birmingham (2011), BSc and MSc degrees from the University of Alexandria, in Mechanical and Production Engineering. Following his PhD, Dr. Essa joined Partnership for Research in Simulation of Manufacturing and Materials (PRISM2) as a research staff leading research projects in cooperation with Rolls-Royce, MTC and the newly established centre CASIM2.

The majority of his research has focussed on the application of finite element (FE) modelling using ABAQUS and DEFORM software to simulate a variety of manufacturing processes such as hot isostatic pressing, additive layer manufacturing, dual-material upsetting, metal spinning and single point incremental forming (SPIF) processes. His process modelling experience extends to the use of Computational Fluid Dynamics in industrial applications using Flow-3D, ProCAST and Sigma Soft software. He developed a numerical model to predict the distortion of ceramic core during wax injection in investment casting.

His research interests include; manufacturing of auxetic structures from superelastic alloys using additive layer manufacturing for defence applications, Net-shape manufacturing using combined material processing techniques such laser fabrication and hot isostatic pressing for aerospace applications.
