Corrosion and Fatigue Training

ABOUT THE COURSE

Corrosion science is often viewed as a “heavy” subject, usually highly chemical in nature and demanding understanding of thermodynamics and electricity. As a consequence many shun the theoretical aspects and find solace in the practical issues, such as the methods used to recognize it, measure it, and protect against it. This practical branch of corrosion study is described as corrosion engineering. However an ignorance of the fundamental theories of corrosion can lead to a limited understanding of the atomistic level mechanisms in operation and hence an inability to deal with cases of corrosion that do not conform to “typical” situations. The lectures therefore aim to introduce and explain these fundamentals in a way which should remain accessible to the majority of participants.
Following a general introduction to fatigue and fracture, with examples of service failures, current and developing fatigue design and assessment methods will be described. The course will go on to explain the importance of crack/flaw analysis in structural design and safety assessment and illuminate its wide range of applicability. It will give a deep understanding of the major results and criteria underpinning modern fracture mechanics, the assumptions behind them and important limitations. Attendees will gain a better understanding of material selection for fatigue and fracture resistance and learn about codified procedures for flaw evaluation.
WHO SHOULD ATTEND
Engineers and scientists involved in the design, operation and assessment of both onshore and offshore structures. Personnel from oil companies, consultancy organisations, classification societies and certifying authorities will benefit from attending this course.

ABOUT THE LECTURERS:

Helena Polezhayeva

Dr Helena has more than 30 years’ experience, and is internationally recognised as a fatigue expert, specialising in the development of spectral fatigue analysis and fatigue assessment procedures for a wide variety of ship types and offshore structures.
Helena also has expertise in fatigue related consultancy and research including fatigue testing and numerical analysis as well as the development and delivery of fatigue training. Helena was awarded a Royal Society Fellowship in 1994 for her Post-Doctoral research
Adam Wojcik

Dr Wojcik is a materials scientist based in the Mechanical Engineering Department of University College London. He has taught across all aspects of materials science for the past 20 years, from basic to the advanced level, ranging from fatigue and fracture, welding metallurgy, biomaterials, through to semiconductor fabrication, and corrosion theory and prevention.
Adam’s research mainly focusses on methods of materials characterisation and materials testing as well as the development of instruments for detection and measurement of crack growth in metals
