Innovative solutions for your material fatigue challenges
Our approach is rooted in a deep understanding of the complex nature of fatigue and the challenges it presents. By integrating advanced software tools such as nCode DesignLife, Ansys Mechanical, and Nastran, we aim to provide realistic and accurate lifespan predictions essential for the success of your projects.
- Stress-life (S-N) and strain-life (E-N) analysis: Our analyses cover both high-cycle and low-cycle fatigue problems, applying advanced material models and fatigue corrections to deliver the most accurate results. These methods are crucial for determining the fatigue life of components under varying load conditions.
The assumption made in the S-N and E-N fatigue analysis method is that fatigue failure occurs once a crack has formed, visible to the naked eye, typically 1-2 mm in size. - Crack growth analysis: When a fatigue crack has initiated (or is already present), we can also calculate the remaining lifetime during the crack growth phase. Some materials exhibit high resistance to further crack growth and can therefore have a significant reamining life after the crack initiation periode calculated with the S-N or E-N analysis methods. This approach fundamentally differs from the S-N and E-N methods and is based on fracture mechanics.
After the initiating of a fatigue crack, the crack continues to grow until it potentially reaches a critical length, leading to the complete failure of the material in fatigue. - Vibration fatigue: We offer advanced analysis of virtual shaker table tests and predict material fatigue in the frequency domain. This approach is particularly effective for evaluating random loads, such as those caused by wind and wave loads, providing more efficient and realistic results than traditional time-domain analyses
- Thermo-mechanic fatigue: Our expertise extends to the assessment of components exposed to high temperatures and creep, which is crucial for parts such as combustion engines, exhaust systems, and fired pressure vessels in the process industry. These analyses help predict complex failure modes under extreme thermal and mechanical conditions.
- Fatigue of welded joints: We offer specialized analyses of welded structures,with seam welds or spot welds, evaluating the lifetime of welded components using advanced methods that take into account the unique properties and challenges of welded constructions.
Fatigue life analysis of the seam welds in a welded component. The fatigue life is calculated both at the weld toe and the weld root. - Fatigue of composites: Our approach for composites includes a stress-life analysis for anisotropic materials, such as short-fiber composites. We evaluate the fatigue strength of structures against industry-standard composite failure criteria, effectively identifying critical locations and load combinations.
