VABS: Going Beyond Linear Elastic Cross-Sectional Analysis

Summary:-Millions to Billions DOFs!- Not suitable for preliminary design.-Not suitable for aeroelastic analysis.-Unnecessary waste of engineers time and computing resources.- Testing is difficult and expensive, particularly for large blades.-State of the art: multibody dynamic simulation integrating both aerodynamic and structural concerns.-Success of this simulation relies on accurate blade modeling to link structural details with blade properties.
