Duration
3 days
Prerequisites
Basic knowledge of Ansys Mechanical
Software used
Ansys Mechanical, FKM inside Ansys
- Understand calculated strength verification according to the FKM guideline
- Implementation of the FKM verification in the simulation
- Discuss your own application
- “FKM inside Ansys” license free for three months
Description
The FKM guideline is a guideline issued by Forschungskuratorium Maschinenbau e.V. (FKM) for computational strength verification for general machine components. The guideline provides a uniformly structured calculation algorithm for all application cases consisting of instructions, formulas, tables and illustrations. In this training course, you will learn guideline-compliant strength verification with “local” stresses in accordance with the FKM guideline for both non-welded and welded components. We will also show you just how quickly the automated workflow FKM inside Ansys will allow you to conduct assessments not only for individual verification items but for the entire structure or a multitude of weld seams.
After this training, you will understand the methodology of computational strength verification according to the FKM guideline. You will become familiar with the procedure for static strength verification and fatigue analysis for welded and non-welded components. You will know how to implement the FKM guideline in the simulation. You will have an overview of the stress concepts for the weld seam calculation.
This training is ideal for calculation engineers, test engineers, designers and anyone who wants to know more about the FKM guideline. You will be able to discuss your own applications during the course.
