FKM Standard

SDC Verifier supports automatic verification according to FKM Guidelines (5th edition, 2003 and 6th edition, 2012) directly inside Ansys Mechanical, Femap, and Simcenter 3D.
Used by mechanical and structural engineers, the FKM Guideline enables accurate analytical strength assessments of steel and aluminum components under both static and fatigue loading conditions.
It supports 1D, 2D, and 3D finite element models and integrates all relevant material, geometry, and load influences.

About Standard

The FKM Guideline (Rechnerischer Festigkeitsnachweis von Maschinenbauteilen) is a trusted resource for analytical strength verification in mechanical engineering and related fields.

First released in 1994, the guideline is based on earlier VDI 2226 and TGL standards, incorporating updated research and practice.
Applicable to steel, cast iron, and aluminum components subjected to static and fatigue loads.
Covers strength checks for rod-shaped (1D), shell-shaped (2D), and block-shaped (3D) components using FEA or BEM results.
Enables assessments across various manufacturing methods: welded, machined, and untreated surfaces.
Addresses static and variable amplitude fatigue strength based on service conditions, temperature, and geometry.

FKM offers a flexible, parameter-driven approach aligned with real-world operating environments, making it essential for ensuring durability and safety in high-performance machinery.

Frequently Asked Questions

What is the difference between FKM 5th and 6th editions?

The 6th edition includes updated material factors, expanded weld classifications, and refined guidance for multi-axial fatigue. It builds on the 5th edition with clearer workflows and modern design updates.

Can I perform both static and fatigue strength assessments with FKM in SDC Verifier?

Yes. SDC Verifier supports both static and fatigue checks according to FKM guidelines, including amplitude-based and variable fatigue strength assessments.

Which materials are supported in FKM checks?

The FKM standard in SDC Verifier supports steel, cast steel, cast iron, aluminum, and cast aluminum—all within defined temperature ranges and manufacturing conditions.

Do I need to define effective diameters manually?

Not necessarily. SDC Verifier can calculate effective diameters automatically, but you can override this with manual input if needed, especially for solid elements.

Can I use FKM verification for welded components?

Yes. The standard includes support for welded joints with proper classification of weld types, notch factors, and thickness correction.

How does SDC Verifier handle fatigue summation?

You can perform fatigue summation using stress ranges from defined load groups. Rainflow counting and service stress history are also supported for advanced evaluation (Enterprise license required).
