9​am - 5:30 pm CET (Central European Summer Time), UTC+2 (Berlin)

Language: English

This training course covers the ”FKM-Guideline Fracture Mechanics” for static and cyclic loading. Besides the detailed assessment procedures, background on the individual topics will be given for better understanding about the procedures. The course is aimed at newcomers in the field as well as experts interested in the concept of the guideline.

The FKM guideline is a standard developed by the Forschungskuratorium Maschinenbau (Research Committee for Mechanical Engineering) – FKM - for static and cyclic strength verification. Due to its broad applicability, the strength verification has become widely used in mechanical engineering and other industries.
