RESEARCH & DEVELOPMENT WORKS

Professor Meguid's research activities are concerned mainly with micromechanics, finite element modelling, contact mechanics and smart structures. He has made a number of major contributions in these areas. Specifically, his micromechanical formulations and models of interacting microdefects in advanced and smart composites, under both quasistatic and dynamic loading conditions, are highly regarded by the scientific community. His research efforts which focus on the development of a new strategy to treat contact problems in solid and shell structures under quasistatic and dynamic loading conditions is not only considered to be highly original and of high quality but also of great industrial importance. His efforts in determining the fatigue fracture behaviour of engineering materials in the presence of residual stresses have been rewarded by a number of research contracts from the aerospace and automotive industries.

 

Professor Meguid has been involved in comprehensive design/analysis studies concerning aeroengine compressor and turbine disc assemblies; partially and fully filled fluid couplings; landing gear for a commercial aircraft; fixtureless assembly; intelligent grippers using smart materials; intelligent gantry robots for removal of land mines; shock absorbers for electrically powered vehicles; suspension systems for subway cars; power steering pump drive assemblies; porous dental implants; finger implants; and external fixation devices, to name a few. Professor Meguid is actively pursuing research on deformation localisation in cellular materials. His work on the crashworthiness of foam-filled ultralight hydroformed automotive structures is well supported by General Motors of Canada, Cymat Inc., Materials and Manufacturing Centre of Excellence (MMO) and NSERC.

 

Presently, Professor Meguid is collaborating with Professor E. Bogoch, of the Department of Surgery at U of T, to improve the design of a number of finger implants. He is also contributing to a major effort by the Department of Dentistry concerning design analysis of dental implants, osseointegration and bone resorption.

 

Professor Meguid's efforts in the above mentioned areas are well supported and highly regarded by his peers. This is evidenced by the list (quality and quantity) of research contracts undertaken (Appendix 2), the large number of Journal publications, reviews of the published work and the number of scholarly addresses given (Appendix 3), and the close association with numerous scientific and industrial organisations and government agencies.
