On the subject

The FKM guideline "Calculated strength verification for machine components" is a standard developed by the Forschungskuratorium Maschinenbau (FKM) for static and dynamic strength verification. Due to the wide range of applications, the strength verification has become widely used in mechanical engineering and other industries. In this seminar, you will learn about the guideline-compliant strength verification with local stresses for both non-welded and welded components. In addition to the theory of the verification, the focus is also on the practical application of the guideline, in which questions also arise for the user outside the actual guideline. These will be discussed in the seminar using practical examples. Learn how to build the right bridge between stress determination in the finite element system and the FKM.



In this seminar, you will learn the procedure for the computational strength verification in accordance with the FKM guideline for static and dynamic loads, both for non-welded and welded components. You will learn how to implement the verification in conjunction with the FEM analysis and which special features need to be taken into account. The update to the 7th edition is intended to ensure that future verifications are carried out according to the current state of the art.
