Static and fatigue analyses and design of welded structures are not always part of undergraduate curriculum. In addition, methodologies concerning analysis and design of welded structures are being constantly up-dated and improved. Therefore there is a need for engineers to get familiar with recent developments in area concerning: theoretical methodologies, computer software, and design of welded structures.
Corrosion and fatigue are the most frequent sources (more than 75%) of failures of welded components. In many instances failures occur prematurely due to inadequate design, manufacturing defects, or inadequate maintenance and inspection.
The degradation of products and structures imposes a significant cost for the owners and operators of plant and equipment. Besides the financial aspects, the possible risk to human life and health is always a major consideration.
Welding is on the other hand the most common method of joining metal structures and components, yet the special considerations necessary to ensure satisfactory performance from a welded joint under fatigue loading are often not appreciated by designers, fabricators and manufacturers.
Various methods of fatigue analysis of welded structures will be discussed together with appropriate choice of the stress parameter and necessary stress analysis method. The course will be devoted mostly to the application of the fatigue nominal stress method (S-N), and the local strain-stress method (ε-N).
- Basic concepts of static design of welded structures; stress quantities used in the static analysis of welded structures
- Characteristic features of fatigue damage and fatigue failures
- Stress concertation and stress distributions in welded structures
- Basic fatigue methodologies
- Geometrical and material effects
- Residual stress effects
Basic courses on mechanics of materials and stress analysis, material science.
The seminar is particularly relevant to people involved in design, optimisation and fatigue assessment of steel structures and machinery components. Therefore attendance is recommended to designers, structural engineers, mechanical engineers, fabricators, welding engineers, quality control, maintenance and inspection personnel, university lecturers, students, and researchers.
The seminar might be useful to the following industry sectors: steel construction, infrastructure fabrication and maintenance, bridge building, transport industry, power generation, machinery, shipbuilding, maintenance and aviation industry, ground vehicles, and earth moving machinery.
Dr. Grzegorz (Greg) Glinka, D.Sc.
Professor, Department of Mechanical and Mechatronics Engineering, University of Waterloo
Dr. Glinka has been with the University of Waterloo, Ontario, Canada since 1989. He was a Post-Doctoral Fellow at The University of Iowa (USA) in 1978 and later he has lectured at the University of Metz, France and at the University College London, England. He holds a PhD and D.Sc. from the Warsaw University of Technology. He has also acted as an expert of the United Nations and visiting professor at The Aalto University in Helsinki, Finland. Dr. Glinka is a specialist in fracture and fatigue of steel structures and mechanical engineering machinery. His research interests include fracture of materials, fatigue of structures, multiaxial fatigue and creep of engineering materials, computer aided design, FEM-elastic-plastic stress-strain analysis, and reliability. His recent research activities concern modeling of fatigue crack growth under random loading and fatigue optimization of welded structures. Dr. Glinka has published over 190 related articles in technical journals and textbooks.
