FKM (6th, 2012) Strength Verification in Mechanical Design

About Standard

FKM-Guideline (6th Edition, 2012) is the updated standard for analytical verification of mechanical components under static and fatigue loading, based on current engineering practices and industry research.

Implemented in SDC Verifier:

Valid for steel, cast iron, aluminum, and cast aluminum structures
Covers a wide range of influences, including material types, weld conditions, surface treatments, and service load profiles
Enables automatic verification in Ansys Mechanical, Femap, and Simcenter 3D

Core capabilities:

Material & Geometric Settings

Effective diameters (auto or user-defined)
RmZ tensile strength input or standards-based values
Surface conditions (roughness, coatings, treatments)
Softening factor for aluminum alloys
Anisotropy factor for directional properties

Weld and Fatigue-Specific Parameters

Welded joint types, residual stress classification
Weld factor, FAT class (per Tables 5.4.1 and 5.4.2)
Plastic notch factors for stress concentration
Hot Spot Stress and Weld Stress integration

🔹 Safety, Inspection, and Risk Configurations

Factors for consequence of failure, regular inspections, and casting quality
Stress occurrence probability and load safety factor
Temperature correction and reference number of cycles
Special treatment for surface-hardened or non-tested castings

This comprehensive standard is essential for projects demanding precision fatigue strength assessment, multiaxial stress handling, and high-confidence design validation in machine-building, automotive, and industrial equipment manufacturing.
