Abstract

<p>Green energy production is one of the most important societal needs of our time. In particular, wind power production is of great importance and its significance is expected to increase even more. Fatigue assessment must be accurate for cost-effective structural designs of dynamically loaded constructions such as wind turbine supporting structures. The Two Stage Model provides an advanced fatigue assessment by using specific cyclic material parameters, as input. These material- related parameters can be determined using the Incremental Step Test. This paper presents an application of the Incremental Step Test. The test results are then applied to the strain-life approach, which is the first step of the Two Stage Model.</p>
