Variability in Monolithic Composite Parts: From Data Collection to FE Analysis
International audienceA main challenge facing the structural applications of composite materials is related to the uncertainty in the material performance due their inherent variabilities. Structural properties of composites are not only dependant of the manufacturing steps, but also on the constituent materials, reinforcement architecture and design choices. By introducing geometrical variabilities into finite element (FE) model through meta-models, the effect of variations in the composite structure can be studied at different scales. To assure that the FE results are in accordance with the real composite structure, the input parameters of the models must be in agreement with the actual material and its configuration in the structure. In this chapter a methodology to study and introduce variabilities into a composite structure FE analysis is presented
