Abstract


A general framework for the probabilistic definition of laminated composite materials and structures is proposed and justified according to quality-driven analysis of typical load-bearing thick aircraft composite components. The approach and its computational implementation are described. Specific variants of the developed probabilistic model are considered for typical laminated composite structures, including variants for 2D and 3D statements of analysis. Representative quantitative examples demonstrate simplicity of the numerical implementation and the interpretation of generated data. In addition, a direct link between the proposed probabilistic definition and structural response of composite materials is outlined. Its quantitative demonstration is illustrated on examples of typical laminated carbon-fiber reinforced composite structural elements under bending load.
