Dr. Georges Akhras is a Professor of Civil/Mechanical Engineering at the Royal Military College of Canada, Kingston, Ontario. For ten (10) years, he was project manager for computer applications, numerical analysis and engineering projects in government and industry.

Dr. Akhras joined RMC in 1987. He is a member of many technical and professional associations. His current interests include structural behaviour, computational mechanics, numerical modelling, knowledge engineering expert systems, composite materials, smart materials and structures and engineering education, and he has published many papers on those subjects.

Dr. Akhras is also President of Cansmart, the Canadian Smart Materials and Structures Group.

Computational Mechanics for Engineering Applications

Computers are omnipresent in almost every aspect of engineering. Twenty-five years ago the emphasis of research was on the fundamentals of data gathering and analysis techniques. During that period, Dr. Akhras developed, for the James Bay Corporation and the Engineering Firm Rousseau, Sauvé & Warren of Montreal, a finite element software RSWLAVAL© for the design and analysis of the underground cavities LG2 & LG4 of the James Bay hydroelectric project in Northern Quebec. Subsequently, as project manager for the Department of Transportation (Quebec), he dealt with computer applications and numerical analysis of many engineering projects involving computer aided design (CAD), finite element (FE) modelling, and computational fluid dynamics (CFD). After joining RMC, Prof. Akhras was a pioneer in the development and implementation of new computing capabilities to produce advanced software such as knowledge-based expert systems: EXMIX© for the proportioning of concrete mixtures, TRUSS© for the maintenance of timber trusses, BEAMEX© for the design of reinforced concrete beam, and ROAD© for the corrective maintenance of road pavements. During that period, a box girder simulating the hull of the ship and the corresponding stiffened steel plates were designed, constructed, tested for ultimate strength followed by numerical modelling and simulation. At the same time, research on modelling using the Finite Strip method, a variation of the Finite Element method, was underway to study the static, dynamic, vibration and stability behaviour of composites and sandwich plates.

The wave of the future in computational technology research will be in formulating and verifying models based on fundamental understanding of physical phenomena. The focus of Prof. Akhras' research is on understanding the fundamentals of the models themselves rather than on solution techniques. As examples of recent activities, a human tibia as well as a deployable space antenna is being analyzed and their modeling capability studied in order to achieve a complete level of understanding and be able to reliably predict their global behaviour.

Smart Materials and Structures

In 1998, Prof. Akhras was elected president of the Cansmart Group, the Canadian Smart Materials and Structures Group. Since then, he has been a leader in promoting the new technology of smart materials, smart structures and smart technologies in Canada and around the world, particularly the computational facets. In 2004, Prof. Akhras was appointed Director of the new RMC Centre for Smart Materials and Structures (CSMS). Fundamental, experimental as well as simulation research on structural health monitoring and smart technologies for civilian (building, bridges) and military applications are underway with collaboration from national and international organizations.
