EN 17149


The EN17149 is a new European standard for railway applications. The fatigue strength assessment of railway vehicle structures based on damage accumulation. The current status of the code is draft.

The code includes nominal and structural stress as well as effective notch stress concepts. Different procedures in combination with Finite Element analyses are discussed. It can be used for steel and aluminum alloys. The procedures are comparable to the FKM guideline. Some elements, such as the thickness correction under consideration of bending, are taken from British Standard BS 7608.

With this new code, measured data or results from multi body simulations can be processed. Variable amplitude fatigue can be taken into account rather than just using the endurance strength for the assessment.

LIMIT® Implementation

LIMIT® offers the modified version of Miners’s rule. The software can be used for the assessment of steel, cast iron, cast and wrought aluminum, as well as welded steel and welded aluminum structures.
