Fatigue Life Prediction of Aluminum Alloy 6063 for Vertical Axis Wind Turbine Application Blade Application
Vertical axis wind turbine (VAWT) blades are fatigue-critical parts that must endure at least one billion stress cycles within their design life. Integrated computational materials engineering (ICME) methodology is used in combination with the Mississippi State UniversityInternal State Variable (MSU-ISV) plasticity-damage model and MultiStage Fatigue (MSF) model to predict the fatigue life of VAWT blades manufactured from extruded aluminum alloy 6063. Multiscale modeling is implemented at various length scales and the MSU-ISV model is used to establish the stress state of the blade, which is passed on to the MSF model to calculate fatigue life. Results from this analysis can be used to optimize the design life of aluminum alloys made for VAWT blade applications.
