Determination of the Fracture Locus of a Cor-Ten Steel at Low and High Triaxiality Ranges. The aim is to provide a snapshot of some of the most exciting work published in the various research areas of the journal. In this study, we determined an aerodynamic configuration to design structures applying composites for large-scale horizontal-axis wind turbine blades. A new aerodynamic and structural design method for large wind turbine blades is presented. The rated power of the wind turbine blade is 25 MW class.
