Gassner spectrum
A Gassner collective is a standard collective of service loads to simulate fatigue damage under variable amplitudes. It helps predict and avoid cracks in weld seam areas.
Physicochemical Mechanism of Action
A Gassner collective consists of a series of loads with varying amplitudes. These loads are used to simulate the fatigue behavior of materials under variable stresses.
Metallurgical Relevance & Welding Risks
Using a Gassner collective is especially important when testing weld seam areas that are subject to high mechanical stresses. Incorrect simulation or inadequate consideration of amplitudes can lead to inaccurate predictions and thus risks such as cracks or failures.
Workshop Practice & Action Instructions
To correctly apply a Gassner collective, follow these steps:
1. Determine the appropriate load sequence based on specific stress situations.
2. Use simulation tools or software to calculate fatigue behavior.
3. Regularly review results and adjust loads if necessary.
