A New Framework and Set of Tools to Quantify Uncertainties in Composite Structures Using Swiftcomp and Dakota
Composite materials are widely used for various structures in industry because of their superior properties like stiffness- and strength-to-weight ratio, and the capability of tailoring the overall properties by manipulating constituent materials at lower level of scope. Multiscale analysis is carried out to capture those properties. However, in reality, uncertainties are everywhere during the whole process of manufacturing. Uncertainties in design parameters and properties of constituent materials will propagate to uncertainties in the overall properties and behaviors. In this work, authors will present a new framework for uncertainty quantification using a new set of tools including SwiftComp and Dakota. An example of a wind turbine blade structure will be presented.
