Strength verification of machine components according to FKM guideline
According to updated 7th edition
Main focus
- Nominal stress concept and local stress concept
- Static strength verification and fatigue strength verification
- Material properties and weld calculation
- Form and notch factors in the FKM guideline
- Example calculations
- Changes and extensions of the 7th edition
On the subject
The FKM Guideline "Computational Strength Analysis for Mechanical Engineering Parts", is a standard developed by the Forschungskuratorium Maschinenbau (FKM) for a static and dynamic strength analysis. Due to its wide field of application, the strength verification has become widely used in mechanical engineering and other industries. In this seminar, you will learn about the strength verification with local stresses for both non-welded and welded components in accordance with the guidelines. 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 of 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 calculation.
Objective
In the seminar, you will learn the procedure of the computational strength verification according to the FKM guideline for static and dynamic loads, both for non-welded and welded components. You will learn how to implement the verification in connection with the FEM analysis and which special features have to be considered. The update to the 7th edition is intended to ensure that future verifications are performed according to the current state of the art.
