Fatigue strength verification
Safety that lasts. The fatigue strength verification shows at an early stage whether your component will remain failure-free even under cyclic loading – reliably, in accordance with standards and economically.
Lasting safety for your constructions
Recognize fatigue. Avoid failures.
A fatigue strength test is a key procedure in mechanical engineering, vehicle construction and other industries to evaluate the service life and operational safety of components under cyclical or alternating loads. Such dynamic loads are caused by recurring forces or moments such as rotation, vibration or pressure pulses and can lead to cracking and failure in the long term.
The fatigue strength calculation shows how many load cycles a component can withstand without damage. For this purpose, stresses, notches and material characteristics are analyzed and evaluated using standard-compliant methods such as the FKM guideline or on the basis of experimental Wöhler curves. The aim is to identify potential weak points at an early stage and verify the operational stability of your design.

Weld seam calculation
Load-compliant design of weld seams for static and cyclic stresses.
Component optimization
Increased competitiveness through targeted and effective component optimization, such as the use of materials.
Fatigue strength verifications are essential when...
Your safety - our responsibility
it is known that loads are cyclical and that the structure is subject to high alternating stresses.
the cyclically loaded system or machine has weld seams in the force flow, as these are typically the weak points.
cracking or failure under real conditions of use should be prevented.
optimization potentials in material use or geometry are to be used in a targeted manner.
the component behavior under load is decisive - the focus is on stresses and deformations.
Advantages of a strength analysis of components
Measurable benefits. Verifiable quality.
Prevention of component failure
A fatigue strength verification can be used to ensure that the component can withstand the loads acting on it. This protects people and property.Dimensioning of components
We determine the required dimensions and material properties to ensure a safe and resilient component. Especially with cyclical loads, it is difficult to estimate in advance.Optimization of constructions
Particularly in the case of fatigue strength, the permissible number of cycles can be greatly increased through clever optimization, which improves the longevity of your components.

Frequently asked questions (FAQ)
Quick answers. Clear solutions.
Which guidelines and standards can be used for fatigue analysis?
We carry out fatigue tests in accordance with the FKM guideline, VDI 2230, EN 1993 and other industry-specific standards. Customer-specific requirements or international standards (e.g. ASME, DNV) can also be taken into account. Please contact us if your standard is not listed!
In which phase is a fatigue analysis useful?
A fatigue analysis is particularly important for safety-relevant components that are subjected to dynamic loads over a longer period of time. It helps to identify critical points as early as the design phase and avoid costly modifications or failures later on.
Can existing components also be evaluated with regard to fatigue?
Yes, subsequent fatigue assessments are also possible – for example as part of service life analyses, conversion measures or when inspecting existing systems. We analyze the current condition and the remaining service life potential for you.
What is the difference between a static and a fatigue analysis?
While the static verification tests the strength under a single or constant load, the fatigue verification evaluates the behavior under cyclic, i.e. repeated stress – typically over millions of load cycles. It is essential for components that are exposed to vibrations, alternating loads or operating loads.
How much does a fatigue test cost and how long does it take?
This depends on the component, the complexity of the load and the information available. In many cases, however, we can make you a concrete offer after a brief preliminary discussion. Please feel free to arrange a free and non-binding consultation!
