World leading FEA and CFD Simulation Services Engineering Company for CFD and FEA and Engineering Simulation. # Fatigue Analysis: Stress-Life Method for Wind Turbines. | What you will learn in this article In this blog post, you can discover the origins of engineering fatigue assessment and learn, based on a real simulation problem, how to apply S–N curves to assess high-cycle fatigue. The results of his investigations are still illustrated today by the S-N Curve (also known as the Wöhler Curve), one of the fundamental tools used to assess fatigue in engineering. In this use case, we demonstrate this concept by simulating the fatigue behavior of an aluminum wind turbine blade, illustrating why such a design would not be practical. It describes the relationship between the stress amplitude S and the number of cycles to failure N for a specific material.
