Analytical Strength Assessment 7th. Ed. 2020 EN | Print

7th edition 2020
232 pages

This 7th edition of the FKM guideline "Analytical Strength Assessment of components" has been completely revised, so that a listing of all changes is not manageable.
The following major changes have been made to the calculation algorithm:
- the ductility was defined with reference to the elongation at fracture,
- the long-term temperature factors were reformulated,
- for the calculation of the plastic support number, the tolerable reference strain was increased by the elastic portion, and the strain hardening factor was introduced,
- the static strength values of welded aluminum components formulated with reference to Eurocode 9,
- the stress definition in the fatigue strength check was extended so that the critical section plane method can always be used,
- the amplitude and equivalent stress checks are formally equivalent,
- the parameters for the support number calculation according to Siebel & Stieler for aluminum castings adapted,
- the applicability of the protective layer factor to galvanized steel extended,
- the limitation of the maximum amplitude under consideration of the mean stress formulated,
- notes on the Wöhler line system added,
- the sign rule for the comparative load factor reformulated,
- a clarification of the decisive load factor in the fatigue strength check added,
- the material tables completely revised,
- the material group "Ausferritic spheroidal graphite cast iron" (ADI) newly included,
- the section with notch factors for shafts with hub seat more closely aligned with DIN 743,
- the fatigue strength verification for welded components based on notch and effective stresses was reformulated, and
- special boundary layer factors for post-weld treatment.
The description of the overload cases F3 and F4 have been removed because of their rather rare practical use. However, their use in the sense of the previous editions of the FKM guideline is still permissible.
