Fatigue Analysis - Software and Theory Explored in UK Classes

Professor John Draper is presenting a free one day seminar - Durability by Design - and a three-day fatigue theory class - Modern Metal Fatigue Analysis - at Safe Technology's training centre in Sheffield, UK, Feb 2-5, 2010.

There have been major advances in methods of fatigue life estimation over the past 30 years. Allowable stresses can now be estimated to an accuracy of a few percent. Much of this knowledge is available in research papers but is not readily available to designers. These classes are intended to help bridge the gap between research and real industrial design. They are aimed at Design and Test Engineers responsible for product durability in the ground vehicle, aerospace, power generation (including renewable energy) and general manufacturing industries; in fact, any industry where metal fatigue is an issue. Academics and undergraduates on mechanical engineering courses will also be interested in attending. No previous knowledge of fatigue is necessary.

The one day Durability by Design seminar covers the problems that can now be solved using durability analysis software for FEA models. A technology update in key areas of fatigue analysis is provided including multiaxial fatigue, the effects of temperature, notch sensitivity and residual stresses. Professor Draper looks at why traditional methods of fatigue analysis get it wrong and gives an introduction to modern methods and why they get it right. A demonstration of Safe Technology's suite of durability analysis software, fe-safe™, is also provided.

The three day theory class, Modern Metal Fatigue Analysis, provides a concise introduction to modern methods of fatigue analysis and their practical application through worked examples and interaction/discussion. Throughout, the focus is on practical application and there is a strong emphasis on what is possible and the pitfalls to avoid.

Attendees will be introduced to the concepts of strain-based fatigue analysis and the more traditional S-N curve methods. Modern theories of multiaxial fatigue are described, together with their application to strain gauge measurements and fatigue analysis of finite element models. Also covered is statistical analysis, crack propagation and the fatigue of welded joints – as well as the merits and disadvantages of different types of fatigue tests and aspects of practical fatigue analysis.

John Draper’s recently published reference book, Modern Metal Fatigue Analysis (2008),forms the basis of the course notes for the three day class and can also be purchased from the EMAS website www.emas.co.uk
