Non Deterministic Approaches

12th AIAA/ISSMO Multidisciplinary Analysis and Optimization Conference

10-12 September 2008
Victoria Conference Centre, Victoria, British Columbia, Canada

For over twenty years, the biennial AIAA/ISSMO Multidisciplinary Analysis and Optimization (MA&O) Conference has brought together industry practitioners, government employees, and academics to present and discuss the latest developments in multidisciplinary design, analysis, and optimization. Multidisciplinary analysis and optimization is rapidly becoming a standard element of contemporary design methodologies. With significant advances in computing algorithms and power, impressive analysis and optimization applications have been successfully carried out in industry, government, and academia alike. Additionally, theoretical developments ranging from new optimization algorithms to approaches for design system robustness and reliability have played a significant role in the ever-growing acceptance of multidisciplinary design and optimization. Historically, the MA&O Conference has provided a comprehensive view of the state-of-the-art. For the first time in its history, the MA&O Conference will be held outside the United States. 

TECHNICAL TOPICS

Course on "Risk Analysis and Structural Reliability"

26-28 November 2007, Paris, France

http://www.asranet.com/ 

The course aims to provide participants with an understanding of the fundamental elements of risk analysis and structural reliability. It will also introduce the concepts of uncertainty modelling in load and strength applications. Practical applications for the safety assessment of engineering structures, considering the key techniques involved, will be highlighted. Emphasis will be on the use of reliability engineering methods in offshore and marine structures.

The syllabus will include: basic elements of the safety case concept, hazard identification techniques, risk assessment, risk reduction, safety management systems, uncertainties in load and strength predictions, structural reliability and the goal-setting approach to safety. The course is intended for practising engineers and research scientists who need to understand the concepts behind risk analysis and structural reliability, to interact with experts in safety management or to begin to undertake a more extensive study of the subject.

Who Should Attend

A major issue in vehicle industry is the presence of variability in the physical properties and manufacturing processes. Deterministic approaches are unable to take into account these variabilities without leading to oversized structures. The necessity of assessing the robustness of a particular design requires a new methodology based on reliability analysis and design optimization through probabilistic models of design variables.

The vehicle lifetime is highly determined by the fatigue life of its components. Variability in the material parameters (Young's modulus, tensile strength, ...) may have a strong effect on the fatigue life. This is demonstrated in this paper for a vehicle knuckle structure.
