“…The Eigenspace Perturbation Method (EPM) (Emory et al, 2013;Iaccarino et al, 2017) is a physics based framework to quantify model-form uncertainty introduced in EVMs. This method has shown reliable uncertainty quantification with low computational cost, and has been applied to a variety of engineering problems including virtual certification of aircraft designs (Mukhopadhaya et al, 2020;Nigam et al, 2021), design of urban structures (Gorlé et al, 2019), aerospace design and analysis (Mishra et al, 2019b;Mishra & Iaccarino, 2017a;Mishra et al, 2019a;Mishra & Iaccarino, 2017b), application to design under uncertainty (DUU) (Demir et al, 2023;Cook et al, 2019;Mishra et al, 2020;Righi, 2023), etc .…”
