The FKM Guideline ("FKM Richtlinie") is the gold standard for analytical strength assessment in mechanical engineering. Developed by the Forschungskuratorium Maschinenbau (FKM), it provides a structured mathematical framework to verify the static and fatigue strength of machine components made of steel, cast iron, and aluminum.
FEA (Finite Element Analysis) verification, design validation, safety factor calculation. 2. FKM-Richtlinie Download: How to Get the PDF
It bridges the gap between raw stress results (often from Finite Element Analysis) and reliable safety margins, ensuring components are neither under-designed (unsafe) nor over-designed (uneconomical). Materials Covered:
Most modern FEA packages include modules that allow for an FKM-conformant assessment: Provides structural tools tailored for FKM analysis. FEMAP/NX Nastran: Uses plugins for stress assessment. fkm richtlinie download file type pdf downloads install
Apply the relevant correction factors outlined in the FKM PDF (e.g., technological size factor, surface roughness factor, and temperature factors).
Steel (including stainless), cast iron, aluminum, and cast aluminum alloys. Recent additions include specific guidelines for sintered steels (published early 2025). Current Editions:
