Systematic analysis of engineering failures is essential for improving engineering designs and make them failure tolerant. However, effective analysis of failure requires knowledge of a variety of issues which are rarely, if ever, taught in a single course. While understanding the growth and propagation of existing flaws is based on fracture mechanics, clues about the nature of failure can also be obtained from the microstructure of the fractured surfaces. This requires grounding in materials science and advanced microscopy. The process by which defects nucleate in a structure, either over long periods of operation or in an aggressive environment, involves an intricate interplay between materials science and mechanics. Experimental techniques in failure analysis depend on a wide range of methods requiring knowledge of optics, electron-matter interactions and the like. Finally, computational methods play a significant role in failure analysis.
Prof Daniel Rittel is a very well known expert on failure analysis. His course on the subject, offerred already to students and researchers at California Institute of Technology, University of Innsbruck, Beijing Institute of Technology, University of Tokyo among other places, aims to bring together the diverse fields of knowledge that must synergistically be used in order to interpret and predict engineering failures.
The Indian experts associated with this course have extended experience in experimental and computational aspects of fracture and failure. IIT Kanpur also has state-of-the-art advanced experimental and computational set-ups for studying problems in fracture and failure. The Indian experts will play a supplementary role in this course by introducing the participants to some of the established infrastructure in this area.
Postgraduate students, researchers and engineers from industries and national laboratories, faculty members from engineering institutes having an engineering degree and exposure to basic mechanics and materials science/metallurgy.
