The NAFEMS Education and Training Working Group wishes to commission a new book on “Fatigue Benchmarks”
This book should be aimed at a graduate level industrial user who is familiar with basic linear FE analysis, but is inexperienced in advanced FE analysis where fatigue life is analysed.
The book should cover benchmarks demonstrating the use ofmodern FE software to analyse fatigue problems and fatigue life methods. The following topics are expected to be included:
- Life prediction methods
- When to use Safe-life, strain-life and damage tolerant approaches
- Crack propagation criteria
- Linear and non-linear material behaviour
- Variable amplitude loading
- Mulit-axial stress states
- Non-zero mean stresses
- Thermal fatigue
What constitutes a good benchmark can be summarised as follows:
- The benchmark should be devised to verify there liability, robustness and accuracy of the FE code.
- The problem must have a reliable reference solution; ideally a closed form analytical solution or alternatively a reliable numerical solution. The limitations or assumptions used in the reference solution must be stated.
- Data input needed to define the benchmark should be kept to a minimum so that lengthy data generation is avoided.
- Ideally, the benchmark should have some educational merit, in order to provide teaching material on particular aspects of fatigue life through a case study.
- Whenever possible, the benchmark should reflect real-life fatigue applications.
- The objectives of the benchmark, and the features it is devised to test should be clearly stated.
The total cost is not expected to exceed £7,000.It is expected that the book will be completed within 12 months from NAFEMS approval.
Potential authors should submit the following:
- A brief description of the main topics to be covered
- Chapter and section headings with an approximate number of pages per chapter
- Timescale for completing the book
- CVs of the authors (Maximum two-pages per author)
Applicants are advised to study existing NAFEMS publications in this field before submitting a bid. The following NAFEMS publication is relevant in this field:
- HT17, Bishop, N, W, M, and Sherratt, F, How To do Fatigue Calculations, 2000.
All proposal should be sent to NAFEMS at firstname.lastname@example.org to arrive no later than 31st May 2014.
Further details are available from the NAFEMS office or by contacting the Chairman of the ETWG email@example.com.
