This paper introduces random-matrix-based uncertainty quantification to prestressed complex structures, which is particularly beneficial for large-scale structures such as aircraft. The proposed Wishart Random Matrix model quantifies uncertainty in critical structural components—mass, stiffness, and damping matrices. The approach is implemented using NASTRAN, Monte Carlo Simulations and Python.
